add commands to toggle settings that control auto behavior

[bhcleek]

Add commands to toggle settings that control automatic behaviors. All the new commands begin with GoToggle, and are suffixed with the name of the setting, but using PascalCase in place of snake_case.

Also moved one function so that all functions called by events and functions that control settings are in the same relative order as the respective events.

@fatih I think these new functions (e.g. s:toggle_auto_type_info()) should be moved to autoload/go/util.vim. At the time I submitted this, I didn't really know how autoloading worked. What do think?

Thanks @bhcleek for the work. I've wrote my comments below. Yes they should be moved to autoload/go but under different files to make it maintainable.

• Can you change the names and append the Toggle to the end? All our commands are like that so you can easily find them.
• Can you add enabled and disabled echo messages. Check out guru.vim how I've added for sameids. I think each function should have a custom logic. So they should be in the associate files

go_auto_sameids -> guru.vim (this exists already under go#guru#AutoSameIds, so don't touch it)

These should be moved:

go_fmt_autosave -> fmt.vim
go_asmfmt_autosave -> asmfmt.vim
go_metalinter_autosave -> lint.vim
go_template_autocreate -> template.vim

• Can you please move the commands to ftplugin/go/commands.vim
