Add vim-githubcomment plugin

Wow, this is far better for reviews than using the website.
Add vim-eighties to mangle windows to their proper width

This still provides a great overview when you have too many windows open, like
I often do.
Use XDG basedir locations for data files

This works *everywhere* I use this repo, but shouldn't really hard code
locations.
Support git config in XDG_CONFIG_HOME
Move bundle menu item to support neobundle config
Set useful paths for generated data files
Ignore all files in external/
Comment snipmate dependencies in neobundle config
Snippets repository renamed to vim-snippets
Add editorconfig repository

A couple of co-workers have chosen to use this, so we'll see how it goes.
Add moonscript filetype repository
Remove spell cache file
Don't echo bufferline to command bar
Add filetype mapping for mutt configs
Require vim 7.4
Use relativenumber in GUI
Add jdaddy repository
No longer using vim-sleuth

The automagics fail spectacularly in a few filetypes.
Set showmatch

vim-sensible no longer sets it :/
No longer using snipmate

Recent versions seem to cause me more grief than time saved.
