UTF-8 and long history
Better color escapes

I noticed zsh was pulling the "bash wraps muh lines on the same lines" stuff,
so I escaped the color calls. zsh no longer has errant wrapping issues at the
moment, so I imagine I fixed it.
Made aliases global

sudo v foo
Fixed RVM sourcing.
Removed echo

It was there for debugging, although I may ultimately create a login message.
Fiddled with RVM PATH lines

RVM is throwing a fit over my default ruby not being in the path. I've tried
everything I can think of, but the only solution I have so far is to call
default ruby, so I went ahead and made my zshrc call it silently.

Still trying to get my .irbrc to look nice. Every time I require a gem in it, I
get a LoadError, and it's apparetly because of how RVM handles gemsets. Ugh.
