Fix RH669942: Add support for packEnabled and versionEnabled

This changeset adds support for explicitly using jars with pack200 compression
and versioning. This requires no server side support, but expects the client
to try and find the right jar and fallback to using uncompressed/unversioned
jars if the versioned/compressed ones can not be found.
