Removing redundant dependencies / using jboss bom

Most of the dependencies that were in the pom were not needed and were
in the wrong scope to begin with. This uses the Wildfly BOM (bill of
materials) to specify the correct versions (and scopes) for Wildfly
8.1.0.Final.
Removing unnecessary attributes in persistence.xml
Adding basic beans.xml content

You don't have to have this, but it helps keep things portable.
Fixing injections

You can't have @RequestScoped Stateless Session Beans (SLSB), so I just
left them as dependent (no scope annotation), which for what they're
doing is probably fine. I've changed the scope of some of the other
things so we're not leaking objects into longer living scopes.

I've also fixed up injections where needed. The reason the
HttpServletRequest was null was because the object containing the
injection was manually created, instead of being created by the
container using injection. If you want container managed services
(transactions, injections, security, etc.) you have to let the container
create the objects.
