Time stats

This morning I made a quick addition to the code that manages my observing logs and added some code that extracts the elapsed times for all my sessions. Using this I've been able to add a new section to my stats page that lists some time-based values.

As of now, since 2005-04-16, I've spent 93 hours doing something related to observing. On average I've spent about ½ hour per session. My shortest session is 1 minute long and my longest is 252 minutes long (although the the longest session is a little misleading because there was a break of about 1 hour during it).
