[jboss-rpm] Updated AS7 spec file and JBoss' packages guidelines

Hiya, I was working yesterday and today to make security module working - and I made it. I introduced also some changes to the spec file. AS7 boots with security and transactions modules enabled. Good sign. There are two things worth mentioning: 1. The way AS7 modules/submodules jars are being copied / added to depmap and symlinked was changed. 2. I started the process of removing the jboss/ directory from jars. Speaking of #2 - please take a look at the "Ouch" box: http://fedoraproject.org/wiki/JBossAS7#Rules_for_JBoss-related_packages I'll go over all packages over the time and remove the jboss/ directory. The only place where it can break are places where we create a symlink to the jars (AS7 spec file, other ant-based spec file). We'll clean that over the time. Please don't add the jboss/ directory to new packages and if you're in the middle of packaging something - please remove it on your own - this will save me some time. Thanks! --Marek
