Mats3 v2: Upgrade to jakarta.jms libraries.

[stolsvik]

Due to the amazingly annoying situation with the donation of JEE to the Eclipse Foundation whereby they were not allowed to employ the "javax." package prefix, all JEE libraries have changed package name to "jakarta.".

This makes for a massive break, which the JMS implementation of Mats3 must handle.

Only way is to split it up into two different versions.

I will finally release a 1.0 with javax.jms, and then a 2.0 with jakarta.jms.
