[Rpm-metadata] updates

[seth vidal]

Uploaded the new createrepo - ver 0.3.3  - changes:
- versioned deps format
- package counts at the top of the files
- uncompressed checksum in repomd.xml

found here: http://linux.duke.edu/metadata/generate/
the rpm is built on fedora core 2

I also uploaded the xmlReader implementation of the import code. Found
here: http://linux.duke.edu/metadata/import/

and I updated the sample files for the new format - located here:
http://linux.duke.edu/metadata/samples/

let me know if anything seems horribly wrong :)
