Opened with Xcode 5.1.1
Added icon support for requires and update_for items in package editor
Completely reworked source list for packages list view

It’s now based on filter predicates instead of requiring packages to be attached directly to the source list objects. This change will allow easy creation of additional smarter source list items.
Moving a package should only update the URL
The predicate for all packages can not be nil
Removed remaining relationships between packages and source list items
Started working on category support
