[jboss-as7-dev] Update AS config schema to 1.3

Would there be any objections to a pull request going in to increment the schema version without adding additional config? The reason I ask is the changes I am working on are going to take a few more days before I am ready to send them in and they involve schema updates so the first change is enabling version 1.3 - in the meantime if anyone else was to also need a schema update the work (actually takes a few steps to update) would be duplicated and would most likely conflict.
