Added OS X framework target
Added github's standard objective-c .gitignore
Updating both Mantle and AFNetworking (both hadn't been updated in a month), and updated to using the non-deprecated Mantle API
Upgraded to modern Mantle transformation API. Unit tests pass now!
Added ignore=dirty flags to submodules
Set OS X deployment target to 10.7 (to match Mantle), and added mention of OS X support to the README
README updates
Deleted deprecated code (almost entirely because it makes mention of ASIHTTPRequest, and I don't want anyone thinking I or anyone else endorses that as a viable networking library).
