Title: DHEK22 - Add a selection button in toolbar

After introducing #102 , add a new button in toolbar to have a selection mode:
- While click (in selection mode), click on page doesn't start drawing area, but start selection (displayed as a dashed rect while dragging). Remove display of area details in right panel (under area list).
- On mouse release, select area within selection rect (reflect selection in area list).
