zsh compatibility

[postmodern]

Currently, chruby does not work in zsh. Some ideas:

• The eval $(chruby --init) hack.
• Write separate scripts for bash, zsh, etc.
• Rewrite chruby to only use POSIX shell scripting syntax.

+1 I only use zsh and I would like to try this out as a replacement to rvm.

chruby won't fully replace RVM (rbenv does a better job at). @mephux would you be interested in working on investigating getting the script working on both bash and zsh? The main blocker is that Arrays in zsh are completely different (indexed starting at 1 instead of 0).

OK, I might have gotten basic zsh support: https://github.com/postmodern/chruby/tree/zsh

Released version 0.1.0, which I tested on zsh 4.3.17.
