User view should show loans

[Sebastian1515]

The user view (library/user-detail/1) should also show the loans of the user. This makes it easier to return books by searching the user name.

I implemented a basic version of it. I think it now competes with the view of "My Loans" as a members loans are now also shown in the profile. I would therefore suggest to remove "My Loans". Do you think it would be better to sort the loans again by returned/unreturned?
