Fix bug: use "python3" open repl instead of "python3.4"
Add search/replace mappings
Remove B2K

- I don't think camelcase motion is actually that useful because it's
  not repeatable.  Moving inside of a camelcase word is only useful if I
  can change one word inside of it.  But that's not a change that's
  easily repeated on other instances of the camelcased word.  I can't
  repeat word motions like I can with ; or n.  So it's a pretty poor way
  to refactor code, better to use an f/t motion or a search or a :s
  command
Replace kien's rainbow_parentheses.vim with junegunn's fork
Remove wellle/targets.vim, implement myself.

- Some kind of bug popped up and I didn't feel like dealing with it.
  Just rewrote it...
Remove base16-vim, add molokai

- Couldn't get base16 to render on tmux.  molokai is as beautiful as
  ever.
Fix bug in grepprg. Add --nobreak option for ag.

- Otherwise output lines aren't parsed correctly by the quickfix list
Remove omni-completion from MegaTab

- It's too much at that point, filetype and keyword are enough for me
Add TodoList function and mappings
Fix SetColorColumn - remove erroneous zero-width highlight

- Also move the function call to a more sensible location
