Make topic muted notifications clearer.
muting: Make topic muted notifications clearer.

The popup that appears when you mute a topic is a bit hard to read,
since nothing makes the topic and stream names jump out from the rest
of the paragraph.  Fix this by using bold around the stream/topic and
also cutting a bunch of unnecessary verbiage.

Tweaked by tabbott to further simplify the language.
