[Building Sakai] mathml support

[Sam Ottenhoff]

Yup, agreed.  It seems like the best solution would be supporting MathJax
everywhere in Sakai.  Then the FMath editor could export to MathML and
MathJax could render the MathML into the visible (or accessible) equation.
 Comments would be appreciated in this JIRA:
