* otherwise, fall back to description if available
* otherwise, fall back to filename
* if both caption and description are available, show caption as
title and show description below the fold; otherwise don't show anything

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).

This takes care of several minor annoyances:
* centralizes all the text processing functions which have been
floating all around the code, and adds proper tests
* filters out invisible elements (sometimes used for metadata)
* avoids merging separate words on HTML->text transformation
* adds caching since doing all this transformations could be
processing-intensive for big chunks of HTML. (This might or
might not be a good idea. I haven't done performance tests, so
this might be premature optimization, and increases memory use.
OTOH these functions are often called in situations where an
immediate UI response is expected (such as selecting a size
from the list) so even small delays would be perceivable.
