compression, wdb testing completed, weekend

I've now added compression (zlib, level 6) for long values (> blksize). That should help with large email attachments.

I've also completed testing wdb. The last two areas were long values and recovery. I'll likely post the (stable?) version to AgileWiki later today.

And with the weekend coming up, I hope to crank out a large chunk of tks2.py, especially as it is turning out to be ever so much shorter than the original. But its going to be interesting when I start working on all the supported queries--hopefully the four indexes I'm reimplementing (RPTC, RVTC, PVTC and TC) will prove adequate.
