Use sort menu as well for detailed view (#139)

Add "Arrange Items" sub-menu to details view (listview).

Changes the behavior if one selects an action that is already applied.
Sort order (Ascending/Descending) will get toggled if the currently
active sort attribute is chosed.

Previously the Arrange Items sub-menu was specific to icon-view.
This means that all the functions where static in abstract-icon-view.c .
Here I have moved all those functions to standard-view (which is the parent class of all views),
now all views will inherit the menu, actions and functions related to sorting.
This is why the line count is 100 lines less is more.
