Fix drag and drop from taskbar to activity pager
The code to handle a window drag from the taskbar to drop on the Activity Pager to add the window to an Activity was broken, because the test to see if the drop location is a running activity still treated the itemId as an integer indexing into an array of running activity indices, rather than an id string that could be a member of the list of running activities. It is not clear whether this is a bug fix or a new feature. The drop handler in PagerModel.cpp I amended is not used when DnDing windows within the pager, but may have been used for that at one point. This also allows the familiar file manager semantics of ctrl+drag = copy, drag = move to be used when dragging and dropping windows between activities using the taskbar and the activity pager applet.
