r7450: removed reference to plugin HeuristicLab.MathJax-1.1 but added mathjax to the list of extlibs to fix the plugin-dependency checker unit test.

I think the default font size is a bit too large. I don't know if this is possible, but it would be nice if formulas could be broken in multiple rows if they're too large (e.g. before or after a term that spans beyond the screen). An additional idea would be to use v₀..v_n in the formula and have the variables listed in a similar way as the constants (maybe in a second column, or pre- or appending to the constant column). This way it's easy to get a list of all variables in the formula.

Line breaking is a bit difficult to get right but should be possible. I don't like idea of using v₀ ..v_n instead of the variable names a lot.

The MathJax script seems to be blocked when HL is started from an USB stick.

r8110: switched back to the tree view as default for symbolic data analysis models instead of the math notation view.
