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

[Marek Goldmann]

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!
