This patch updates devel/raknet to version 3.08.
Version 2.0.13 was an old version and faced a checksum mismatch problem
because the port was downloading a generic RakNet.zip file (with no
version). This new version of the port uses a fixed version to ensure
the port will remain fetchable. It also now uses sourceforge as main
I'll take maintainership for it.
