First round of bugfixes after the opening of the public beta!

- New words in the dictionary
- Bugs fixed in HTML Checker tag stack which rejected <IMG> and <LI>
  and had a potential infinite loop
- Multipart handling now handles Windows-uploaded filenames correctly
- Bug fixed in PostOperations that was causing nuke to fail and scribble
  and hide to succeed but throw an internal servlet error
- Enhanced conference listing now gives a better activity report in conferences
- Top Content font enlarged
- Null posts now work (they used to in WebbMe)
- Slippage display corrected
- Probably a couple of other things I can't think of just now.
