Selection tool: do not select relatively large modules 

To avoid situations when a large footprint covering most of the board
area (e.g. shield connector) is always selected, even when user clicks
in a seemingly empty spot, a simple filter has been added. In case
the footprint area covers more than 90% of the view area, the large
footprint is not selected. This way large footprints do not disturb
editing when the zoom is high enough.
