This change leverages the existing `gitcommit` syntax rules to apply the
same formatting and highlighting settings to pull request messages when
they are edited from Vim.
* `noexpandtab` will ensure tabs are used instead of staces when tabbing
or auto-indenting.
* `softtabstop=2` isn't needed because we are already setting
`tabstop=2` in our `.vimrc`.
Add suggested Go configuration for Vim into the `ftplugin` folder and
the vim-go plugin. We may use this as a template for adding further
language-specific settings in the future for languages that aren't
universally used by the team.
* `fatih/vim-go`: The de-facto Golang Vim plugin.
* `softtabstop=2`: As a side effect of setting how "large" a tab is in
insert mode, Vim is able to delete tabs with the backspace key in
Insert mode.
* `compiler go`: Necessary for plugins using the `make` command, such as
vim-dispatch.
* `listchars=tab:\ \ `: Don't highlight tabs as "»·" as if they were
problem characters in go files. Also recommended for *sh files and any
others which which should also be using tabs.
* `go_fmt_command = "goimports"`: Tell vim-go to use the `goimports`
command rather than `gofmt`, which attempts to find dependencies and
adds them to your import statement.
Vim's documentation advises that buffer-specific configuration based on
a filetype should be performed via a file in `$HOME/.vim/ftplugin`:

This change moves CSS/Sass-, Git commit message-, and Markdown-related
editor settings into `ftplugin/gitcommit.vim` and
`ftplugin/markdown.vim`, and rewrites those settings to avoid using
`autocmd`, letting Vim execute `setlocal` when a file of the filetype is
determined or set.
* Set up Vundle in vimrc.
* Delete old copies of vim scripts.
* Bundles are automatically set up as referenced submodules.
* Ignore .netrwhist files given presence of submodules.
* Set up vundle in install script.
