New functionality added:
- 'hide' meta file to list files that should be 'nohist' in the IDB
- 'ops' meta file to list files and associated ops
- 'depends' meta file to list prereqs for the specfile.
Several new functions where introduced and a few old ones where
updated.
Fixed a bug in create_idb which resulted in all toplevel image
descriptions being set to the first one listed in image.conf
Extended subsys.conf to use wildcards to match files
for the subsystems
What's missing currently is the ability to check
if there are unpackaged files left in the staging
area, like rpm does.
New functionality has been ligthly tested
