Add support for the "-c" JBossAS command line option override to select the server configuration in arquillian.xml

Please add support for the "-c" JBossAS command line option to the arquillian.xml configuration file. Out of the box Arquillian is only using the "-c default" option.
It would be very nice to be able to select the server configuration to boot in containers that support lifecycle.

Here is how it could look like in the configuration:

<jboss:container>
<jboss:jbossHome>/path/to/jbossas</jboss:jbossHome>
<jboss:bindAddress>127.0.0.1</jboss:bindAddress>
<jboss:httpPort>8080</jboss:httpPort>
<jboss:profile>jbossweb-standalone</jboss:profile>
</jboss:container>

Thanks
