Fix build of net/mutella on CURRENT and upgrade to 0.4.5
ports/net/mutella does not build on 5-CURRENT with GCC
3.4.x. One of the fixes in the new version of mutella is
to allow it to be built with GCC 3.4.x. The attached patch
updates mutella to the most recent version which allows it
to be compilable again under -CURRENT.
