Lighthouse has a new layout. Prefer the old one? Return to the old layout, and switch back any time from the link at the top of each page.

Use shelve instead of sqlite for cache db

#53

sqlite cache db for dgpe brings lots of problems (like #45 [GetMatches] DatabaseError: database disk image is malformed), and the possibility of switching to shelve for a cache db should be contemplated.

However, the change must be benchmarked! Getting blocks from the DB is a very important bottleneck of dgpe.

    Bah, now that I removed the threaded mode from all Cache instances in PE, and now that Clear Picture Cache doesn't choke on corrupted DB anymore, I'm not sure it's such an important problem. I'm sure shelves bring their own lot of problems too.
