With apologies to anyone who gets a hundred merge conflicts
because of this :)
We had several different prefix styles (mlb-, mw-mlb-, mw-mmv-,
mw-mmv-mmv-, a few unprefixed), which was getting annoying,
and will be confusing to wiki editors who are trying to figure out
where a given style comes from. Such changes are better done before
going live because it breaks all local CSS tweaks on the wiki,
so I am renaming things now (also removing some stuff which wasnt
used anywhere).

I went for this option because it was the fastest to implement.
I think we should wait until we make the change to core to expose
image dimensions before we consider switching to another strategy.
