- Documentation improvements: improved and updated the block module documentation.  Patch #44 by Al.  We should add some real-life path examples!

- Fixed the "blog it" image size.  Patch #49 by Al.

- Some SQL performance improvements to the forum module.  This should also be more PostgreSQL safe.  Patch by me.

mysql> SELECT n.nid, n.created AS timestamp, u.name AS name, u.uid AS uid FROM forum f, node n LEFT JOIN users u ON n.uid = u.uid WHERE f.tid = 2 AND n.nid = f.nid AND n.type = 'forum' AND n.status = 1 ORDER BY timestamp DESC LIMIT 1, 0;
==> 0.63 sec

changed to:
