Identify slow requests

[jonodrew]

I'm not completely happy with this yet.

I've written some helper methods to grab all of the 'things' a member is attending and find them once, when the controller method is called. This replaces the map loop that generated two queries per event.

However, I think there's some clash here. The set of Event, Meeting, and Workshop ids will have some overlap and the tests will therefore be flakey. Advice welcome

I'm interested to know more about the savings you hope to make. I just loaded the production front page in 3.42s will your changes reduce that?
