Added my personal theme

An informative prompt that gives you hg and git repository info, as well as return code, RVM/rubenv info, and standard hostname, path, user. Relatively quiet and unobtrusive colors, yet pleasing. Screenshot at <http://www.flickr.com/photos/79770035@N03/6994931488/>

Stolen mostly from <http://stevelosh.com/blog/2010/02/my-extravagant-zsh-prompt/> and alanpeabody.zsh-theme from Oh-My-Zsh. Left prompt is modified version of the Bash prompt by AntiGenX <http://hintsforums.macworld.com/showthread.php?t=17068>
