Augustin Cavalier 4448758b3e app_server & Interface Kit: Rework cursor reference management. 
We can't allow applications to reference/unreference cursors,
this is a safety/security violation, and it being done improperly
lead to the reference counts becoming incorrect on the app_server
side.

Change AS_REFERENCE_CURSOR to AS_CLONE_CURSOR and adjust the Cursor
code appropriately. (In the future, copying BCursor without Clone'ing
the data in the case of custom cursors could be accomplished with
client-side reference counting.)

Then rework CursorManager to remove cursors at once on team deletion,
and otherwise clean up cursor reference management to let the
reference counting handle things.
