Update to latest GNUstep core libraries.

Update dependent packages with more recent releases.
Remove old and bit-rotted ones.
Switch to using clang 3.3 and libobjc2 1.7 by default, so modern Objective-C features work out of the box and remove a lot of configurable options for sub-optimal (and, often, unsupported / deprecated upstream) configurations.
Take maintainership of GNUstep-related ports.

Several of the ports left in have scary warnings which mean that they are likely broken in lots of cases.  Future commits will fix them.
