A runtime environment nows needs
    - bin/
    - etc/
    - platforms/

- update packing for FOAM_EXT_LIBBIN and newer FOAM_APPBIN
- pack OpenFOAM source via 'git archive' for consistency with
  the git repository (use -nogit option to revert to manual packing)
- combine foamPackBin + foamPackThirdPartyBin
- add foamPackThirdPartyBinAll (like foamPackBinAll)

- relocate service scripts into bin/tools
- use more standard 'tgz' instead of 'gtgz'

- handle ThirdParty-VERSION properly

- handle wmake/utilbin/ location

- should the wmake/rules/* really be packed with a binary distribution?
  I think this is just left over from before.

  - removed legacy foamDiffSourceList, foamPackChanged
  - added foamPackDoxygen for separate distribution of docs
    handles -prefix option
  - misc. cosmetic changes
