I've gone ahead and committed the new page protection UI. This allows seeing
exactly what a page is set to, and logs a bit more information; so no more "hey,
is this page really protected or just protected against moves?".
It's a bit more complex, but hopefully not too scary.
Additionally there's a new level between unprotected/default permissions and
sysop-only; this is set up on en.wikipedia.org
and will restrict edits by
unregistered users and accounts less than four days old.
(This is to implement http://en.wikipedia.org/wiki/WP:SEMI
There's now a timestamp field on the user table for the registration date, which
is used to calculate the age (this'll be included on newly registered accounts
but is NULL on older ones).
The age setting replaces the percentage formerly used for the sitewide move
