Fixed normal bug EXT-4347 (Moving object contents to inventory opens files, changes menu)

Implementation details:
 * Added new LLViewerInventoryMoveFromWorldObserver to watch moved items via their Asses UUIDs. It is instantiated only once due to drop events are sent separately for each item while multi-dragging.
 * Existent LLOpenTaskOffer observer uses it to exclude watched by LLViewerInventoryMoveFromWorldObserver items from own processing.
 * Removed dependancy on LLPanelPlaces in open_inventory_offer(). Openning of offered LM via group notice moved into an appropriate section (processed by LLOpenTaskGroupOffer)

Known Issues:
 * If Script item is among the dragged items from object to inventory it will be the only selected item in the inventory panel.
    Reason: it does not have its own Asset UUID and processed via LLOpenTaskOffer when should not.
