accessible with a referer.

Also adding the pycurl scraper for Westminster, just in case it is useful to remind us how to do stuff later.

The info url situation here is not really good enough. 
All we get is a page with the last 7 days apps on it with no info urls.
I'm using that page as the info url for the moment, but it will obviously
be no use after seven days...

have had to give the search url in all the info urls. Comment url works fine for each app.

Add scrapers for Merton and Conwy (PlanningExplorer)

Add Blackburn and Greenwich (acolnet sites - patch from Peter Collingbourne.
Fixes to Ocella parser (also from Peter). Adds Bridgend, Castle Point, Great Yarmouth, Havering).
Fix typo and escaping in getinvolved (patch from David Sheldon).

This site is absolutely rubbish: 

1) It's impossible to link to the info page - needs a cookie. I've put a link to the search page for the moment.
2) Many applications have no description. I've put the text "Description Missing" when this happens.

we don't have postcodes.

Encode all output as UTF-8.
