Replace BBCode in the Wall block with TinyMCE

[Aaron Wells]

For some reason the dusty but omnipresent Wall block is the one place in Mahara where we still use BBCode. We really ought to swap it out there for TinyMCE, or keep it as plaintext but do a Twitter/Facebook style autodetection of links.

But given that we use TinyMCE for comments, I think it would make more sense to have TinyMCE for the wall block as well.

Implementation note: Wall posts are currently stored in BBCode, and parsed immediately before being displayed. So we'll need an upgrade script that parses and re-stores them as HTML. Or perhaps continue (silently) parsing them for both BBCode and HTML, upon display?

It'd be nice to be able to eliminate the *very* old and no longer updated BBCode parser library that we're using. On the other hand, we'll kinda need to keep it for that upgrade script anyway. :-P
