Pagination for Upcoming Events list

[joedolson]

It would be nice to be able to have some kind of pagination on the upcoming events list. Even just a 'load more' would be something.

The DB query to make that happen is pretty ugly, but should be doable.

Current query is related to current date. Moving to a new page means re-centering right after the last event displayed, setting 'before' to 0 and setting 'after' to $before + $after.

Slating for 3.5, but with a very realistic idea that it might be punted.

I think that a better path might be a completely new upcoming events widget that has a simpler logic. But I think it's too late for me to try and shoehorn this into 3.5; moving to 3.6.
