important form-fix for actor new(that one with ajax) ->read more

I changed form_for with fields_for in the partial part, this way the whole new site only contains one form and the submitbutton is now moved from the partial into the new ( the 'main' view). If you plan to add more stuff in the same form, use --> fields_for(:some shit) do |fields|
Merge remote-tracking branch 'origin' into scopes
Added a rudimentary support in the actors#create view.
Optimized the actors#create view in means of db queries..

Tried to save references to scopes into informations => fails with:
undefined method: '__bson_dump__'
