- qfn.fpd: package names now also include the variant (for now: SiLabs,
  VHHD-2, or VHHD-6)
- qfn.fpd: inlarged center pad of QFN28-SiLabs (was QFN28) from 3.25 mm
  to 3.3 mm
- qfn.fpd: reverted QFN32-VHHD6 (was QFN32) to original geomtry
- qfn.fpd: introduced QFN32-VHHD2 for the ATmega32U2
- qfn.fpd: distribute solder paste in little islands (in progress)

8703fc1a0b qfn.fpd: added measurements and improved design of the central pad
- qfn.fpd: where were no measurements at all - added them
- qfn.fpd: parametrize 0.1 mm border between central pad and land pattern
  and increase it from 0.1 mm to 5 mil (recommended by Adam Wang)
- qfn.fpd: define solder paste of central pad separately and give it a 5
  mil border to the pad edge, 10 mil to the copper edge (parameters
  recommended by Adam Wang)
