Prettified test case names as displayed in Xcode.

Test class names have “Test” or “Tests” removed from the end if applicable.
Test method names have “test” removed from the start, and the rest split into words and lowercased.
E.g. “-[FooBarTests testIsExtremelyQuux]” becomes “FooBar is extremely quux”
