Merge the wildfly BOMs into a single BOM

We had some discussion on the jbossdeveloper list [1] about merging the current wildfly/eap boms into a single one instead of a separate bom for each use case.

The only problematic BOM might be the hibernate3 bom because this includes dependencies which conflict with the hibernate 4 bom. So the hibernate 3 bom will probably need to remain separate.
