WIP
autocomplete 'g' alias
tweaked gemrc
new, more sophisticated install script & org

Install Script can now handle linking files to places other than
just ~. Useful for OS X app preferences you want to keep synced.

Downside, install.rb is now kind of a complicated mess. I could
refactor it and fix it up, but this version at least will work.
Merge branch 'complications'
