Fix classes in persistence.xml-s
Upgrade wicket and wicketstuff to 6.10.0
Migrating from glassfish to jboss 7.1.3 (#44)
* add jboss-as-maven plugin so we can deploy with maven
* create jboss-app.xml in the ear with the agent realm
* modify mail jndi resource url
* switch from wicketstuff-javaee-inject to wicket-cdi, replace @EJB annotations
with @Inject (these one-liners caused the big commit, sorry:)
* remove unnecessary ejb-jar.xml

Web services:
* remove jackson-jaxrs-json-provider dependency and related code: in jboss,
json serialization works as expected...
* class level @Context doesn't work on beans so I removed @ManagedBean annotations.
We use beans.xml so we can use @Inject to inject EJBs and stuff.
* simplify web.xml
Fix bug in entrants webservice: I moved enums in a subpackage earlier (606db8f646c)
