WFLY-886 BZ 961273 - Fix subsystem version registration
Removing as7 and as8_style.css
WFLY-330 - Allow defining server http port (and other basic properties) via jvm arguments
Obs: This is working, but the final tests on subsystem.xml fails because the final value is not int.
Merge branch 'master' of https://github.com/spolti/wildfly
