activemq: 5.8.0 -> 5.13.2

It seems Activemq was "split" in to 5.8.0 and 5.12.1 only to keep from
trampling someone on 5.8.0. This is to the point of not upgrading the
default, but making a new activemq attribute specific for 512.

As far as I can tell, there is no good reason to stay providing 5.8.0,
so this is the proposal to delete it.

Note: There are over 1,000 fixes between 5.9.0 to 5.13.2.
