Reword main intro to be more factually accurate

Facts that were wrong:

 * SR is held at the University of Southampton:
   The competition is in Newbury this year, and kickstarts are at a
   variety of places (listing them in the intro would be silly).

 * Run by students at Soton and Bristol
   Several of our organisers and volunteers are not at Soton or
   Bristol.

I think there's more work to be done here later, but this patch makes
the intro correct at least.

Add Hampton School to teams.json

Hampton school was not in teams.json. This is a bad thing, because
apparently things use it.
