[jboss-as7-dev] Testsuite simplification (runs faster!)

Hi, I've simplified the testsuite. Before, it's execution plan was a bit chaotic - things being wildly copied around without much design in it. Now it works recursively as it should. That means: testsuite/ copies from build/target/... or -Djboss.dist, and configures things used uniformly by whole testsuite: IP, datasource, users, etc. Then, in every submodule: - AS is copied from ../target/jbossas to target/jbossas, and makes it's own changes; - target/jbossas is copied to target/jbossas-something; those are the instance(s) to be run. The pom.xml's have changed a lot, so now I need someone to review and merge it before it gets too complicated to resolve rebase conflicts. Thanks, Ondra
