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.

e.g. {{refimprove}} on enwiki - there is an icon of a book that is only
meant to be illustrative on the page. It interferes with the page's image
collection and the flow.

Everything is under mw.mmv now.
(Also, I cut down on the number of direct global instance references a bit.)

* Fixes the bug where the browser hash would get nuked on
foreign anchor clicks
* Moves the hash handling back into the mmv itself
* Adds test coverage for the hash nuking bug
