lib/search: code style cleanup

Couldn't even `shellcheck` until I did a first pass...too much noise! ♥

lib/search: fix `_bash-it-flash-term()`

1. `$text_black` isn't a parameter provided by _Bash It_. Typo?
2. `$bold_yellow` is meant for prompt strings and putputs `\[`; ditto `$bold_red`.
3. The color was never returned to normal after.

lib/search: fix usage statement `_bash-it-search()`

SC2154

lib/search: `shfmt`

My apologies to future `git blame` hunters ♥

lib/search: code cleanup

Improve `_bash-it-erase-term()`, `_bash-it-flash-term()`, `_bash-it-rewind()`, `_bash-it-search-result()`, and `_bash-it-search-component()`. Minor tweaks to `_bash-it-is-partial-match()`, and `_bash-it-search()`.

pathmunge tests

main: Glob for *.bash properly when path contains spaces

- `shfmt`, `shellcheck`
- Clean up legacy/compatibility code to simpler control flow
- Move theme stuff down to where themes are handled
- Don't use `**` as _Bash It_ has never before set `globstar`; this eliminates varying behavior by environment; this alsö fixes users having any not-enabled themes under their custom dir.
- Lose weird Mac-specific alternate shell startup file (Bash loads startup files on Mac the same as it does on any other *nix system.)
- Place `composure.sh` init all in one place

main: adopt `_bash-it-log-prefix-by-path()`

lib/reloader: adopt `_bash-it-log-prefix-by-path()`

lib/appearance: `shellcheck` && `shfmt`

reloader: `shellcheck` && `shfmt`

Rewrite globbing per `shellcheck`'s SC2013 recommendations, and standardize whitespace.

lib/preview: `shfmt` && `shellcheck`

Fix theme file path globbing when $BASH_IT contains any spaces.

My apologies to future `git blame` hunters ♥

uninstall: `shellcheck` && `shfmt`

lint: add lib to clean_files.txt

lib/theme: `shfmt` && `shellcheck`

My apologies to future `git blame` hunters ♥

lib/colors: `shellcheck` && `shfmt`

Alsö, clean up `__color_rgb` to just use a regular if block.

lib/p4helpers: `shfmt`

My apologies to future `git blame` hunters ♥

lib/githelpers: `shfmt` && `shellcheck`

My apologies to future `git blame` hunters ♥

lib/theme: don't redefine battery_char()

Combine the two definitions for `battery_char()` so the second one doesn't just overwrite the first one. Do one or the other, not both.

Don't evaluate if `battery_percentage()` is available at load time, evaluate it at run time.

lib/command_duration: `shfmt` && `shellcheck`

My apologies to future `git blame` hunters ♥

lib/theme: `shellcheck` SC2154

These variables are referenced by themes already linted.

lib/theme.githelpers: unbound varbl

lib/theme: don't use `date` for `$THEME_CLOCK_FORMAT`

main: simplify flow of lib loader loop

Eliminate the separate loop for `vendor/init.d` since it's just as easy to glob it in the `lib` loop.

lib: delete `appearance.bash`

This adds *three* lines to `bash_it.sh`, and two to `plugin/base`. Just not worth an extra file requiring special handling.

main: load custom theme

Allow for simpler directory strucutre when loading theme from `$CUSTOM_THEME_DIR`/`$BASH_IT_CUSTOM`

make aliases load very late

...and update all the tests...

preexec: add helper functions to loader

Define the helper functions for `bash-preexec.sh` immediately after importing it, rather than in `lib/theme`.
- `__check_precmd_conflict()` and `save_append_prompt_command()` are generally useful and not theme-specific.
- Add matching `__check_preexec_conflict()` like `__check_precmd_conflict()`, and alsö `safe_append_preexec()`.

preexec: work around upstream

Alsö, move `set +T` in here.

test/theme: make fewer assumptions

Literally copying a line from the source to be tested is perhaps not the best way to test that code. 😉

That said, we do want to verify that the function was actually loaded.

TODO: actually test the function.

install: use `.bashrc` and notify user

The logic to guess whether to use `.bash_profile` or `.bashrc` was buggy and wrong. Just use `.bashrc` and either automatically fill in a `.bash_profile`, or notify the user that they need to edit their `.bash_profile`.

completions/sqlmap: use `_command_exists`

Addresses Bash-it#1632

completion/fabric: no need for `_command_exists`

If we're already inside the completion handler for `fab`...then it's a bit silly to check if `fab` is installed.

plugins/go: simplify _bash-it-gopath-pathmunge()

plugin/history: no need to set a trap
Instead of globbally clearing `$HISTTIMEFORMAT` and setting a return trap to re-enable it, just make it local to the function.

Also, set the defaults in a way that is happy with read-only parameters.

aliases/general: minor fixes

- Don't define some aliases if the target isn't installed, use _command_exists to check instead of `type` and `which`.
- Use `$EDITOR` for the editor for aliases about editing, excep the `sudo` ones because maybe you want those specifically?
- Fix `ls` aliases to match their common definitions (-A instead of -a: don't show '.' and '..' when displaying hidden files).

themes/base: use `type -P` instead of `which`

Avoid external binary `which`. Use built-in `type -P` instead. Uppercase `-P` forces a path search to avoid hashed matches and functions/aliases and whatnot.

completion/grunt: shellcheck

completion/subversion: load system completion

Load the completion script from the subversion package installed on the system, instead of bundling a copy. This addresses Bash-it#1818.

NOTE: If `completions/system` is enabled, then it will load this same file anyway automatically.

plugins/battery: lint

plugins/xterm: not just Xterm

plugins/thefuck: lint

plugins/todo: lint

plugin/base: use `_bash-it-component-item-is-enabled()`

completion/git: use `_completion_exists()`

plugins/alias: remove old `SC2154` flag

This is no logner needed because the `local` keyword was moved higher up in the function.
