yam-0.7.2-noisos.patch

From: Inertia <technoyippie$gmail,com>

Patch is something that was just bugging the hell out of me :)  It
adds a 'cache' to the determination of a dists 'isos' so that it doesn't
calculate the values every time.  I did this simply because it was
bugging me that I would see the message 'no isos found' more than once
during a run.  I also increased the verbosity necessary for that message
to show up, but that's just my personal preference.
