- in preparation for adding an optional '-reconstruct' to a few utilities
  re-use as -lreconstruct library

- move related stuff there too
      src/decompositionMethods/decompositionMethods
      -> src/parallel/decompositionMethods

- added missing namespace qualifiers

- Unless the points(), cells(), patches() methods are called, the classes
  should know maintain a lightweight representation for as long as possible.

- bugfix: old-code used xferMove() instead of xferCopy() when creating the
  topology mesh - causing const pointField& to break if the code order was
  changed

- relocate blockMesh from src/meshing -> src/mesh

- solves problems that can occur when checking $PWD and links are involved

- also have it use LIB_LIBS to always load finiteVolume

- change name of environment variable from $WM_OS -> $WM_OSTYPE
  as a better description

- this seems to be the most sensible solution.
  The changed time stamps on the links doesn't seem to bother make at all.

- avoids problems with finding files based on FOAMversion
  (reported by Mattijs)

- added wmakePrintBuild -check, -update, -version options
- only update .build cache when explictly requested and
  from within the wmake Cver rules
- use -check option to avoid unnecessary remake in src/Allwmake

  - keyedSurface is similar to triSurface, but uses faces
  - meshedSurface is sorted in regions and should be more memory efficient
  - surfMesh is the placeholder name for an OpenFOAM native surface format

 * started with polyDualMesh, but add mesh reader/writers in the future
