Update of the port to version 0.5.3.
Patches from the previous port (0.51) have been merged into the main source tree and are no longer needed.
Version numbering scheme changed from 0.5x to 0.5.x. This change confuses portupgrade but is consistent with the project's direction.
Cleaned up Makefile.
Edited pkg-descr to reflect new project homepage.
Updated distinfo and pkg-plist.
Please submit updates in diff format as described in the porters Handbook.
