add option to renumber the nodes in .msh files (to avoid gaps in the sequence)

fixed indexing bug when the external view and the current view don't have
the same number of time steps

don't use the "manual" numbering the extrude demo: it creates bad habits
for new users

pretty print

better fix for discrete curves: we don't make any assumptions on the
node numbering anymore (and just regenerate the connectivity)

generalize previous fix

small fixes so we can mix discrete curves with regular curves and mesh
mixed surfaces

a new, more flexible plugin: Plugin(Warp)

better msg window show manag

smaller default polyg offset

make COlor and Hide/Show commands work with discrete entities

fix interactive mesh drawing + initial_only aniso

make "initial mesh only" option visible in scripts

draw interactive Delaunay in correct coordinate system

- fix discrete surf (for the 100000th time)
- new Status N command in parser to force mesh status
- create reverse discrete curves

reverting last change: Matthias' fix does not work

trying Matthias Melcher's fix for the delete widget crashes (this fix
does not require to derive our own popup button class)

fix+cleanup

workaround for Read_Mesh limitation when reading discrete closed
curves (missing last vertex due to List_Insert...)

fix crash + cleanup jf's msg

remove the 3 year clause (after which the BYER could do whatever he wants
with a MODIFIED version of the sources)
