Leading-edge brim takes part in the outer-wall-first rule

Browse Source 
The first-layer rule that prints the outer wall first when a brim is
attached to it, and the brim_type change rule that regenerates the
perimeters for it, only knew btOuterOnly.  btLeadingEdgeOnly, the belt
brim at the part's first contact, is an outer brim too.
