Remove vm info from prompt
Color helper functions
Refactor
Remove gem_home
Separate .zshrc

Alias file
Change some colors/messages
chruby_auto in chpwd, not preexec_functions
Fix word jump boundaries

I think the `set -o emacs` has to come after the `select-word-style`.
Good-enough version of gem groups
Namespace gem groups by ruby engine/version
