Fix a regression where changing certain settings wouldn't trigger a proper settings.

Later, I suspect that I'll create some sort of string that tags the settings that the message was rendered with. This would actually reduce the amount of work that has to go on. This is mostly just a "Is this sane?"
Push MTM up somewhat.
Fix a thing that happens with bouncers, apparently.

I don't know if this is a regression or not. But whatever, it works.
Fix an edge case where an empty buffer occasionally causes a conversation to not properly get unlinked.

Oops.
New feature: Change the color of the notification LED on new notification.

It's fairly colorful. Default is changed to 100% white.

We're using ColorPickerView for this -- It does a good job and a fairly decent job being consistent across all variants of Android.
