Sketch out a status delta.
Flesh out the status delta.
Abstract out the string array creation.
Remove status API from GTRepository.h/m
Sketch status API in a category.
Re-implement status enumeration.

This time we use our GTStatusDelta objects.
Fix ARC complaint.
Xcode project updates.
NSArray+Pathspec -> NSArray+StringArray

It was never meant for just pathspecs so that name didn't really make
any sense at all.

This also makes the method slightly more resilient to arrays with more
than just strings in them. Generics in Objective C would sure be nice!
Unnecessary double import --;
Import GTRepository.h rather than all of ObjGit.
Update catch-all header.
Project changes that XDacted seemed determined to miss.
Don't initialise with a nil delta.
Go back to pointer school Danny.
Options typo --
Add the status delta to the catch-all header.
Add a test spec stub and test for untracked files.
Remove the repo+status spec from the iOS lib target.
Add tests for untracked, modified and deleted files.

This is just in the working directory right now. Need to figure out the
best way to change stages in this test.
