Subject: [PATCH] .vimrc: Don't set 'statusline' if we're using AirlineTheme

- If Airline plugin is active, no need to set 'statusline'.  Setting
  'statusline' can temporary mess up the statusline when re-source'ing
  .vimrc.

- Allow opt-into using Airline powerline fonts. Use Airline powerline
  fonts in GUI Vim.
