[IMC-bristol] calendar

1) Needs some styling?

2) Doesn't display any events on the initial page - it would be good to see a 
list of upcoming events.

3) Pop up window is annoying.

4) Seeing events a day at a time is a bit limiting - I imagine a view across 
day / week / month would be better.

But not bad - stick the imc banner at the top, stick in some events, and link 
it from the bristol main page somewhere, plus a link from the publish page?
