added File->Clear + changed behaviour of File->New (now just adds a
new model)

allow smaller fonts for palettes (test with "-deltafontsize")

use display list for 3d arrows (approx. 2x speedup on my laptop for
large vector views) and spheres

removed static quadrics (wrong when \exists multiple gl contexts),
replaced with correct(?) init in drawContext

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

changed -part command line handling

without recompiling

There's no new functionality for now: PLEASE TEST THAT EVERYTHING
WORKS AS IT USED TO BEFORE.

reparametrization through harmonic maps enhanced

  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

- replaced "Mesh.ContrainedBackgroundMesh" by "Mesh.CharacteristicLengthFromPoints" and
  "Mesh.CharacteristicLengthExtendFromBoundary"

- fixed MED IO when numComp > 9

untabify

rewrote Pplugin(Triangulate) to use our in-house divide and conquer algo
removed triangle from contrib
reactivated OCC STL meshing
