Instead of always downloading offline installer and then run installation manually, would be good to have online version of installer that would let:

1. start installer via JNLP
2. select if EAP/WildFly should be installed too

(1) Should be easy to implement, because it requires only excluding update site bits from jar, provide URL for update site and create JNLP configuration;
(2) Requires EAP download integration into IzPack (would be good if IzPack has supported online installation itself)
