Made init into a proper bash script
Add much better autocompletion with ido, some little things

Add ido completion everywhere, including smex for command completion. Lots
of nice little customisations as well.

Try to make emacs package management automatic (grab the package during
init if it's not already there).

Clean up various little bits: old commented out code rearrange stuff...

Small keybind changes.

Run python through bash to make sure we get the correct path etc. from
bashrc.
