Remove obsolete code for stream subscribe buttons.

Browse Source 
In 18e43895ff we replaced
stream subscribe buttons with stream links.  The new feature
has been well tested and well received for over a year now,
so it's safe to remove the older feature at this point.

Older sites will have super old messages that still have the
rendered markup; this commit does not attempt to address those
situations.  Most likely, clicking on an old button in the old
message will either do nothing or look like a message reply.
