Reorder bash aliases
Minor reorganization and commenting in vimrc
Simplify programming vim keymaps
Change vimrc

- Don't lose selection when shifting indent level. I got used to doing
  this with shifting once, losing selection, and '.'-ing as many times
  as I needed the block shifted. The new way isn't faster but makes more
  sense from an outside perspective.
- Actually edit virtual block as a BLOCK that can extend off the edge of
  lines. Super annoying when I need to do that and vim clamps to EOL.
- Add tpope's vividchalk as a plugin, although I'm not using it.
- Modify Go line length from 92 to 80. Makes more sense and more likely
  to fit on another dev's screen.
