Added `be list --sort *` for user-selectable sorting.

Also added libbe.bug.cmp_last_modified, which handles part of
9ce2f015-8ea0-43a5-a03d-fc36f6d202fe.  To do better we could extend
the RCS framework.

I also transcribed a few emails from the be-devel list onto their
relavent bugs and closed a few bugs.

Finally, I removed some left over InvalidValue cruft.
