Title: Bring over the helpful cleanups.

1. Ensure the changelog is in ascii
2. Allow post-download patches to come from a directory instead of from a single set of files.
3. Allow rpm patches to come from a directory instead of a single list of files
4. Update smithy so that the epel rpm location can come from somewhere not epel (if desired)
5. Ensure we cleanup the 'negative' phase files correctly at the various phases.
