This commit prohibits that the special-page MathShowImages
tries to display information that are not enabled via
config.
A typical example is that the Specialpage tries to
render PNG images for IE<9 even though texvc was not
set up. This was reported as

The PNG fallback for old IE versions worked
only if the PNG image was already stored in the
database.
This change enables the Specialpage that displays
the PNG images to create new PNG images and to
show them directly.
To test this commit you need an old IE version
(IE<9). If you don't have access you can use
an online service such as http://netrenderer.com.

This special page is not intented to be used interactively
and its title is not translatable, so it shouldn't be shown
on Special:SpecialPages.
