Add support for WildFly 9

Now that WildFly 9.0.0.Alpha1 is out, we need to make sure it works properly with JBT/JBDS.

I played with it a little, tried to start/stop, deploy a project and so far I haven't seen any issue.

Other than the one expected that is - when you add the server, you get a warning that the runtime version doesn't match - it detected 9, but 8 is expected. We need to deal with this somehow.

Runtime detection doesn't work. It find the server (although with a strange Type of "WILDFLY-FULL"), but doesn't actually add it.
