Implemented the correction of Anton Blanchard's git pull request #180 

"Antenna checker should ignore vias in partial mode".  I changed the
implementation by moving the correction into the antennaAccumFunc()
subroutine so that it skips the area calculations for the contacts,
avoiding unnecessary computation.  Otherwise, it's the same (vias
do not contribute to the surface area of the antenna when calculating
antenna area in "partial" mode).
