Disable keyboard shortcuts while a move or area selection is in progress

[Daeron]

While moving objects (holding the mouse button) and hitting ESC, the move should be canceled. Currently when the ESC is pressed while moving, the move is done (and no confirmation appears even if there were more than 20 nodes), and also a bogus move of 0 nodes appear in the command history after the "correct" move.

When a move or area selection is in progress and a keyboard shortcut is used that can apply to the current selection, the command that was requested via the shortcut is done. In the case of move, the move is also done and added to the command history, and a new move is instantiated and carries on with the selected (can be different) objects.

eg. moving a way and pressing "o" will make the way circular and continue the move, pressing ESC will unselect all objects and add a bogus line in the command history for 0 nodes. Other tools produce different results.

While the move or selection is in progress, ESC should abort the action. Additionally, undo should work while a move is in progress and work similarly to ESC,
