Work on Notification fragment

Started working on the notification fragment. Have done most things like
fetching the notifications from api and we can delete nots aswell.
Sorted on date. Also added dark versions of camera icon. Created
DoelibsNotificaion class. TODO: Maybe do nicer data update for the list.
Add functionality to accept decline (registrations and renews).

Notification fragment ++

Finnished the notification fragment, all types works, also I added some
api calls. There is the post request left to renew accounts. I also
added so that the auth cookie is gathered opon login and stored.
Borrowings send user to title page when pressing item. so TODO: fix
renew.
