htmlize

[Gareth]

Just added this now because I needed it:-

You can htmlize some text based on a regular expression.

Params
------------
1. RegExp to split the text
2. HTML to be enclosed round the text. It uses a {text} placeholder to
replace the text.
3. Joining character to complete the join

There's a bug in the Hackvertor main code with params, when using the
a comma, this is due to the regular expressions struggling to match
either a param or text. I hope to fix this soon when I have time
