Due to the nature of BBScript, extra testing is needed. Requires full documentation of both bbscript1 and bbscript2.

This is required for complete adoption of changes in #117

BBScript1 documentation partially complete. Remaining page: https://github.com/RpNation/bbcode/wiki/BBScript%3A-BBScript-1%3A-DOM-Manipulation
