Related to #132.

- gcc/g++ always being used

STYLE: spurious unsetenv WM_COMPILER_TYPE (csh only)

- more stringent cleanup of ThirdParty settings for wmUNSET

- better cleanup, avoid collisions between implicit and explicit cases

- remove duplicate 0/ files from the repository

- output as dictionary format instead of PtrList.
  Makes it easier to manipulate (changeDictionaryDict, foamInfoExec).

3rdparty updates



See merge request !49

If a side is not yet assigned to a cellZone (but the neighbour is)
and the surface is not related to a faceZone, assign the neighbour cellZone.
Fixes #156

- provide a static profiling::print(Ostream&) method to output
  values to a log file.

- For example, decomposePar use multiple simultaneous Times.
  So permit multiple initialization without a warning. (issue #157)

BUG: memInfo not activated by -profiling option (fixed #157)

mapNearestAMI: move normalisation to AMIMethod.

Avoids cells shared among processors to be counted multiple times and having
weights > 1.
