/**
* Convert plain text to HTML.
*
* OVERVIEW OF HOW THIS CLASS WORKS:
*
* This class stores an array of tokens that should be replaced by something,
* or something that should be prepended.
* The "token" member of convToken is the text to search for. This is a
* substring of the desired token. Tokens are delimited by TOKEN_DELIMITERS.
* That entire token will be replaced by modText (if prepend is false); or it
* will be linkified and modText will be prepended to the token if prepend is
* true.
*
* Note that all of the text will be in a preformatted block, so there is no
* need to emit line-end tags, or set the font face to monospace.
*
* This works as a stream converter, so data will arrive by
* OnStartRequest/OnDataAvailable/OnStopRequest calls.
*
* OStopR will possibly process a remaining token.
*
* If the data of one pass contains a part of a token, that part will be stored
* in mBuffer. The rest of the data will be sent to the next listener.
*
* XXX this seems suboptimal. this means that this design will only work for
* links. and it is impossible to append anything to the token. this means that,
* for example, making *foo* bold is not possible.
