Use relative line numbers
Add git-smart replacement

All I ever used with git-smart was the nice rebase + log stuff on git
pull. Replicated the important parts of that in 8 lines of ruby. Overall
success, I think.
Replace x script with simple aliases

Apparently, since Xcode 4.6ish, if you open a directory with Xcode it
will try to open a workspace file contained in that directory, falling
back to a project file if one isn't found. Since this is duplicating my
script, I really don't need to roll my own solution.

Also, adding a x-pre alias for opening projects with the Xcode 5
Developer preview.
