Remove java 6 requirement of EAP from installer

There are two strings I would like removed from the installer:

Step 4
Please note that JBoss EAP 6 requires Java 6 or higher.

Step 5
(Java 6 is required to run JBoss EAP 6)

I think this was added when we still supported running of JBDS with Java 5, but now that JBDS needs Java 6 I think it's not needed to point this out explicitly.

Also, in Step 4 there's this:
JBoss Developer Studio works with Java 6 and has been tested with OpenJDK, Oracle and Apple JDK.

• Here I would add Java 7 to the mix - we test that too.

And last, EAP should be Red Hat JBoss Enterprise Application Platform (in Step 5).
