Removed powerline in favor of the one in ELPA.
Add collection of snippets.
Remove ERC from startup.

ERC isn't loading correctly, and breaks startup.
Fix package initialization order.
Fix autocompletion issues and add yasnippet.

Autocompletion was taking a very long time, turns out I had some nice
presets in init.el, but they were written by the cc-mode
hooks (d'oh!).

Removed overriding the TAB key for things.

Added yasnippet to perform context aware autocompletion.
