Source Parser: Parsing text with BBCode style tags

This class can be used to parse text BBCode style tags like [PIC="logo.gif"], [IMG PIC="photo.jpg" BORDER=0], [B]text[/B] etc.

It invokes given calllback functions when open and close tags are found passing the attributes of the tags. The callback functions can return text that is used to replace the tags that are found.

Optionally, the class can turn URLs and e-mail addresses into HTML links. The e-mail addresses can be encoded using Javascript to prevent harvesting by robots.
