[jboss-as7-dev] Changed arguments…can we do better ? :P

[Brian Stansberry]

This implies then two separate files for setting these things, given 
that we want setting them to be externalized from 
standalone.sh/domain.sh itself.

Such a solution would require that JBoss Tools parse the file since we have a chicken/egg problem with VM launching on standalone, and we don't want to have a JVM launching a JVM in a standalone setup (adds too much time to boot). It might also require that we write a native launcher on windows.
