[dev] Possible replacement for Text_Filter_BBCode

Aside from XHTML (a laudable goal, but one that could be taken care of  
with tidy also if that's what you need), does this add any features or  
fix bugs compared to the current parser?

To be honest this is a pretty little-used part of Horde, so to add a  
much more complicated parser here, we'd need a pretty big reason.
