Subject: [PATCH] Fix for fatal caused by static call to MathRenderer::getError

MathRenderer::getError() uses $this, so it should not be called statically.
MathInputCheckTexvc should instead call its convertTexvcError method, which
constructs a MathRenderer object so it can call its getError method.

This code is pretty awful. But this way it won't throw fatal errors all the time.
