(Additionally this removes redundant copied code, and simplifies how necessitas projects work and are built.)

We have to be careful to load certain bundled libs (maybe only the plugin .so) in the delegate class loader, so I could break certain apps by making such a switch. Need a way to categorize the type of bundled lib, in order to decide which class loader to use.
