Major vimrc overhaul coming.  Update Readme.
Replace NeoBundle with Vim-Plug

- NeoBundle is too fully featured for my needs.  I want a simpler plugin manager
  without all the bells and whistles
- Additionally, NeoBundle's syntax was very verbose and started to clutter up my
  vimrc.  It started looking like configuration vomit.
- This is step one of my new "Zero Friction" vimrc policy - to remove, fork,
  replace, or configure any apps that cause any amount of friction whatsoever.
- I'm very happy with this change.  Vim-Plug is fast and simple and handles all
  of my use cases for a plugin manager as of this commit.  I hope to one day
  make my own fork of it to reduce my dependency on the original plugin.
Remove junkfile.vim - unite plugin

- The plugin is buggy and I can implement it myself in about 20 minutes.
- "Zero Friction"
Remove unite-session

- It was always buggy, never restored my tabpages correctly, and kept opening my
  files in read-only mode.  If I need this functionality again, I'll turn to
  obsession.vim
Remove vimfiler

- I'm reducing my dependency on the Unite ecosystem.  It's a great idea, but it
  never felt quite right to me.  Not sure why, maybe it just didn't fit my
  workflow.  Or maybe it was the bugginess of most of the Unite plugins I used.
- Netrw comes builtin to Vim and it's insanely powerful. If I need file explorer
  functionality, I'll combine netrw with tpope's vinegar.vim
Remove unused Unite mappings
Move ColorScheme fixes into autocmds

- Links Comment to ToDo on all colorschemes, not just the ones set in my
  SetBackground function
- Fixes GitGutterBackground for all colorschemes as well
- This will allow me to use more colorschemes than just the ones bound to
  ToggleColorScheme and still get the tweaks I've made to fix these small
  problems
Add wellle/targets.vim

- Enhances text objects with default seek behavior
Add Luna and Sol colorschemes
