Patch V2

OK, I added a parsing function for MathML Length, similar to the one in Gecko and I used that to parse the mspace attributes (and mfrac at linethickness). For the moment, unitless, % and px values should work, but I'm still not quite sure about how to handle the other CSS units.

@Martin: Any idea about how to convert the other CSS units to pixels? I tried things with style()->fontMetrics().xHeight(), style()->font().spaceWidth() or even style()->fontMetrics().unitsPerEm(), but that does not seem to work very well. There are probably functions in Webkit to do that conversion?
