MassOnTime: show time for events.

This being my first real foray into spice maintenance, I am sure I got a
number of things wrong.

- This seems like a lot of work to be doing in the template portion.
- The Dates are going to be local to the user, not the church.
- My code is not nearly as compact as some JS expert/purist might like.

Regardless, this is an attempt to fix #1094 at which I will keep working
until I get it right.
Merge pull request #1096 from mwmiller/bon_mot
