GitLab

Initial implementation of a new plugin system, so that people can managed which aliases/functions they want.

adding my zsh theme -- only difference from robby's being that i'm using white instead of blue for legibility over brown

instead of just git

The key here is not using MENU_COMPLETE which autoselects the first
entry, but using AUTO_MENU which displays the menu but autoselects
on successive tab hit.

Also, do not use zstyle menu yes because that somehow overrides
the setopts.
