Issue 22: comma still inserted after topic, program or series
http://code.google.com/p/npr-simile-timeline/issues/detail?id=22

New issue report by jgtynan:
The tests in lines 220 - 278 here:

http://code.google.com/p/npr-simile-timeline/source/browse/trunk/qglite.js?spec=svn80&r=80

are still putting in a comma after the ids for topic, program and series.
Even if there is only one id selected.

This is not breaking anything, so that's good. The browsers all seem to be
forgiving of this, as is the NPR API not making any complaints.

I'll add this in as a bug. My thinking is that I may need to use a switch
statement instead. It's likely there is a simpler way to do this.
