I've updated RHUM.

The old version(s) used Perl modules for parsing RPM headers. This caused conflicts between versions of RedHat due to changes in the module. This version uses the rpm binary, so it should work across all versions of RedHat. Also, It now supports an unlimited number of update directories and the command line interface has been improved.
