This is just fixing the IDEA Style template that got corrupted
during the renaming to activemq.
I also fixed the copyright header on the template
and renamed the code style names
I'm not creating a JIRA for this, since this is a small change not affecting the codebase
https://issues.apache.org/jira/browse/ACTIVEMQ6-3
We are renaming packages from activemq6 to activemq as that's more generic and version independent
The previous commit renamed the directories. On this commit now I'm changing the code.
If we changed the code and the directories on the same commit git would remove and add a lot of files
without recognizing the renames.
