Extracting description from HTML

...it says:

"The first “block” in the text becomes the “description” (used in show-blog and search results.)"

We need a solution for this that handles HTML added TTW as well as HTML sent in by mail. Most content types (e.g. wiki) will need a variant on this for display in search results.

We're just following the same policy as KARL2, which we could trawl for the code for the HTML or text cases. Or, just reverse-engineer the policy, which I believe is seems to use html2text.
