Added whereami shortcut to pryrc.
Added some copy pasta magic.

- Supposedly there's a way to have vim and tmux use the same keybindings
  for consistency thusly ending the mental dissonance that is C-w/C-a.
  However, it maps C-l to movement, and that's annoying because that's
  how I clear the screen. Need to rethink this strategy. Also, it didn't
  seem to work anyways.
House keeping! More shortcuts!

- Added some node.js aliases.
- Cleaned up the list of themes that I enjoy.
- Enabled the Jira plugin.
- Disabled Growl port forwarding setup.
Added kaleidoscope for sourcetree diff/merge tool. Added rerere to defaults.
