* (bug 34828) Fix MathJax initializer to operate on images as well as text form 

Warning: this piggybacks on 'alt' text and can be broken if a manual alt text was specified on a <math> bit. Needs to be more nativey.
Also cleaned up the conditional setup code since we're already only called when a <math> is present.
