================================================================================
++pcbnew:
Fixed:
bug that crashes pcbnew when removing all footprints
(in connection calculations, pointers to pads not reset)
bug that crashes pcbnew when filling a zone
if a module has a trapezoidal pad
(trapezoidal pads are not yet implemented in zone filling,
they are now calculated as rect shape (todo: a better handling) )
