print 1D elts in unv format + fix 2nd order 1d elts in unv format

indent + cleanup messages (somewhat)

fix gcc warnings + disable BDS optimization for now (it leads to wrong
results with gcc 4; maybe we should have more intelligent tests in
configure or in the makefiles to enable/disable optimization depending
on which compiler is used)

make it possible to add second order vertices for a mesh read from
a file (without cad)

disable the "manually add edges" for now

Don't reinitialize the symbol tree in OpenFile.

(We don't reinitialize the option database, so why should we reinitialize
the variables? Using a single global symbol tree we can again define
variables with -string "" on the command line.)

add fixme for extract volume in 2D (orientation of quads)

update email

currently we cannot bundle Metis with the sources

if the mesh is partitioned, save the partitions in the .msh file

add missing copyright headers

more compact STATUS labels

put STL operations in a new submenu

cleanup STL remesher GUI

Don't set CustomMin and CustomMax to the Min/Max values of the view: it
can be confusing when saving options. Instead, provide buttons in the GUI
to set the custom values to Min/Max if so desired.

always save the surface elements in unv format (not just when the surface is
not part of the boundary of a volume)

small cleanup + don't enter post stuff in select mode at the moment (we
might want to change this if we want to select post-pro views in the future)

instead of drawing in immediate mode (in-between Draw() calls) in HighlightEntity,
just redraw the whole scene. It's slower, but on modern machines it should be OK.
This way we can deal with vertex arrays and mesh highlights easily. I will revert
this change if too many people complain...

- made meshed curves/surfaces selectable with the mouse
- better selection algorithm (use depth info to find the "closest" match)
