new PostProcessing.ForceNodeData to force saving NodeData datasets, even for potentially discontinuous list-type datasets

Fopen deals with non-ASCII filename paths on Windows.

- getfunctionspaces now returns a nodalBasis instead of polynomialBasis
- reversed order for saving elements in GModelIO_MSH - makes things simpler for subelements
- taking msh file version into account while exporting data files (PView ...)

- fixed MED node ordering
- polished 64 bit Cocoa Mac OS X FLTK version
- updated copyright

fix STL export of quads

- fix bb computation to avoid model jumping around when adding points in z=0 plane
- pass interpol matrices as ref

  did in high
* added mesh generation error log summary
* removed Parallel subdir (this is now handled by the message class)
* removed Box subdir and consolidated batch processing in a single
  routine
* made List_T into a class
* reduced dependencies in Pview*.h so we can eventually add the post-pro
  interface to the public API

- deprecated "Complex Volume"

untabify

change new post API to allow multiple meshes in a single view (different
meshes in different steps)
