Add pagination support to Events in the API

/api/events.json now accepts the ?page querystring, e.g.
/api/events.json?page=2 or /api/events.json
Add pagination directive to angular frontend

Big thanks to @michaelbromley for his work on this.  Source can
be be found at https://github.com/michaelbromley/angularUtils/tree/master/src/directives/pagination
Remove page querystring from Events link in header
Load pagination directive into the angular app
Use pagination directive in Events view

Pagination is now handled via the pagination directive with
asynchronous data.  The server returns a subset of the total events.
The directive looks at the 'limit' and 'count' fields to determine
how many pages to generate
