- 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
