URRS - exclude "current rooms" from the blue visited link option for the sidebar

[Tyler-H]

Currently we can select whether we want visited links in the sidebar of a chatroom to turn blue. This is all well and good, but the sidebar checkbox currently affects the "other rooms you're in" section as well, giving us this situation.

I don't think we should be turning the room links themselves blue like this, as, by their nature, the contents of that link will always be changing, thus the notion of marking it blue as a reminder that "I've already visited that link" isn't of value.

This can be fixed by excluding the #my-rooms UL within <div class="sidebar"> from the rule by whatever code means you like.
