How can I customize the highlighting?~

All the highlight groups used by vim-go are prefixed with `go` (e.g.
`goType`) and are defined in the files in the `syntax` directory. To change
the highlighting for any group, add a `highlight` command for the group to
your vimrc. To turn off the highlighting for any group, add `highlight link
group-name NONE` (where `group-name` is the name of the group whose highlight
you'd like to turn off) to your vimrc.

Some people may wish to highlight Go's builtins as keywords. To do so, one
should simply add `highlight link goBuiltins Keyword` to the `vimrc` file.
