core-pr-4

This module have been "re-forked" from DBC as it have been fundamental changed. So it's not the providers that logs into the library system at not the wayf module.

I will recommend that this module is forked from ding2tal to ding2.
I think that different approaches have been tried an this was the one that ensured that all the right hooks etc was called correctly. But we could create an "improvement" ticket on it?
