Switch from rvm to rbenv
Add tpope's vim-surround
2-space indents for json
Remove ruby abbreviations

These cause more problems than they solve. Like going weird when I try
to write example code in a docstring
Recognize markdown and liquid files
New CtrlP mappings

Use actual ctrl-p combination when I want normal behavior. Use <leader>t
when I want to clear the cache.
Don't retain selection after indent

There's no need for this. Use use . to repeat last indent command, or u
to undo it.
Remove spellcheck mapping

I don't use this enough to require a mapping
