* Added rvprop=size to prop=revisions. Can get the size of all the
revisions. The size will not be shown if it is NULL in the database.
* (Experimental) list=allpages now allows to filter by article min/max
size and protection status (thanks to [[en:user:madman]] for the
idea). The database performance of this addition might be so severe
that I might have to remove or restrict it.
* list=exturlusage XML element's tag is now 'eu' instead of 'p' to be
more consistent with the other results.
