[gatein-dev] AS7 packaging improvements

I plan to change gatein.dev value for AS7 from 'jbossas7' to three alternatives: 'jbossas710', 'jbossas711' and 'jbossas712' in order to improve UX and cut down on regular erroneous usage ( https://issues.jboss.org/browse/GTNPORTAL-2523). Any objections to that? Also, I've committed some fixes for occasional crashes on startup, so update from upstream master if you are experiencing problems. - marko
