Calendar and Countdown enhancements

[Brandon Martus]

I got a tiny bit of aligned free time and motivation tonight, so I worked on some of the CD-Events features I talked about above.

You can go and mark your attendance at past and future events. You can also see what teams attended an event, as well. The team attendance data is just random stuff I put in when testing, so if your team isn't listed, please wait until I ask for corrections until you start reporting it.

The layout and everything else WILL change (a little), so don't freak out if you don't like how something looks or if it's missing data, etc.

As always, report any comments, suggestions, or problems you may experience.
