Major revamps to the template parser. Fixed a few security holes that could allow PHP to be injected in untimely places in TPL code. Improved Ux for XSS attempt in tplWikiFormat. Documented many functions. Backported much cleaner parser from 2.0 branch. Beautified a lot of code in the depths of the template class. Pretty much a small-scale Extreme Makeover.
