Subject: [PATCH] Update api.py

- made the plugin it render 'latex', 'Latex', 'LaTeX' processor as well (beside 'math')
- changed the loading time to "onload" from "configured", since we had some problem rendering with trac 1.4
- for the same reason: installed MathJax locally
- Implemented pairs for inline math:
        \( ... \) marks inline math
        $$ ... $$ marks block math
        \[ ... \] marks block math
