controller should have access to their views

[renepickhardt]

when working for example with a band controller it would be nice to have a possability to retrieve its view so that one can use the getter ans setter of the view to fill it with data.

It would also be nice if a controller would have access other variables too, e.g. to it's unique identifier (e.g. the muid) to work with the entity.

All handle methods in controllers now have access to the view object, since its both passed by parameter and returned. Done with commit 294c369. I will look into how we can make variables accessable.

@lukasschmelzeisen if we fix bugs we should mention the bug id in the commit message this is useful if one wants to search for a bugfix in git log he can grep for it
