gobby fails to compile with clang

[jhowarth]

Both Apple clang version 4.0 and current clang svn fail to compile gobby 0.4.94 due to the error...

gobby 0.4.94 clang fix

[jhowarth]

The fix for the explicit specialization errors under clang is pretty trivial. The attached gobby.patch allows gobby 0.4.94 to compley compile under Apple Clang 4.1 from Xcode 4.5 on Mac OS X 10.7.5 by moving the declaration of the serialize namespace to the front of the Gobby namespace declaration in code/util/config.hpp.
