The way categories were handled made it impossible to add anything
after them (they always ended up as the last child of the parent
container). This commit fixes that, and also moves the repo link
behind them (as required by #270).

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).
