Add room color setting to avoid sending private msgs to public rooms

With a bunch of rooms in the left list, it can become difficult to keep straight which one you're actively in. I'm already sending work chats to friends on skype (some coworkers still use skype only), but earlier today I sent a bunch of msgs to my coworker into the main room. No big deal as it was work-related, but annoying.

Ideally, I would like the ability to assign a color to each room/person that applies to the border around the chat entry field or the text itself—not the background color please!—so I can tell at a glance when I'm chatting in the wrong room. If not that, at least change the appearance of rooms vs. private chats.

Yes, it's easy to look at the left to see which room you're in. But as the day wears on or you get busy, it's easy to forget that you switched rooms.
