BOM file should contain depchain included

We have two dependencies to be used with ShrinkRes:

BOM - to be included in dependencyManagement section
Depchain - to be included in dependencies section

The split allows user to override dependencyManagement (e.g. overrided shrinkres version from arquillian-bom via importing Shrinkres BOM.

However, user still needs to reference version to depchain even if BOM is there.
