Use Xcodeproj 0.5.1
Remove Xcodeproj monkeypatch
Remove old Commander files
Replace Commander with Slop

Commander was too inflexible for our purposes, and lead to duplication.
Slop is a much nicer and lighter weight command line parser. As a side
effect, this also allows users to run multiple individual commands.

Fixes #33
Bump version: 0.7.1
AppCode specific files added to ignore-list
Remove the Podfile.lock from the default gitignore

We no longer need to ignore this as of CocoaPods 0.17. We originally
ignored the file because of merge conflicts that were caused by CocoaPods
reordering the lock file on write, but that issue has been resolved and
we haven't seen any continuing issues in testing.
