Editing info on how to deploy UPS

Edited text and included WF info as per https://github.com/aerogear/aerogear.org/pull/348

There are two different UnifiedPush Server wars
* For WildFly, unifiedpush-server-wildfly.war
* For JBoss AS, unifiedpush-server-as7.war

In #348 I wrote different sections for each container.

However, in both cases (WF/AS) the `unifiedpush-auth-server.war` needs to be deployed as well
