FUSETOOLS-1132 - enable debug on server adapter launches

I was able to launch under debug (debug icon and menu item enabled).  I had to start the debug perspective manually but once there the server was under debug and I could suspend/ step/ resume any thread.  I didn't have sources available but tested minimally on Apache Karaf 2.3, APache ServiceMix 4.5 and JBoss Fuse 6.1.  Run launching is unaffected.  Since it's such a trivial change - suggest we merge it in and play with it for a while.
