"Coming Up" bill detail can show very long list of activity

Per feedback from a user, this list can be long and annoying. Consider adding a way to limit the number of items that show up on a summary page.

That should never be like that. There must be a bug somewhere in here, or in a calling function:

That code takes care of flushing previous "upcoming" notices, since they shouldn't accumulate like this.
