Support for FAR 0.14.3.2 - PartInFrontOf and AoAsign fields no longer in FAR classes

 Removed use of PartInFrontOf and AoAsign fields from FAR which are accessed via reflection as the fields no longer exist. Checked with ferram4 via irc that just removing use of them should work ok - brief test launches/atmospheric plane flight showed things seemed to be ok after doing this on my dev build.
