Minor site update
Not too many user visible changes, but this update includes a database migration and I like to push out such updates fairly quickly, before too many other changes accumulate on top of them.
Changelog
Here's the full list of changes, in reverse-chronological order:
0ef7f8b Update tweet preview field every 5 seconds
bb14daa Avoid explict array sorting in specs (using =~)

ed84482 Revert "Fix Rails bug #2266"
90e4543 Require wikitext > 1.5.1
2ddfa62 Update wikitext cheatsheet with relative link syntax
Only a couple of tiny user-visible changes: tweaks to the wikitext cheatsheet and some CSS changes. Several of the changes involve the testing infrastructure and don't directly affect runtime behaviour at all. Some minor clean-up. And the migration I mentioned before, 'Remove "spam" attribute from all models which have it', which is discussed in ticket #1264.
