Tristan Porteries e5bfa98d0f Expose bullet shape margin to UI.
The margin value is exposed into the UI for shape ressource.
This value can be modified through set_margin and get from get_margin
or by using the property margin. Each time the margin is modified
the associated collision shape is recreated and the margin value is
used in ShapeBullet::prepare.
