force focus on OpenGL window when adding points

- fixed a couple of warnings

- JF: bds.classify crashes in recur_tag on simple examples (demos/sphere-stl.stl)

small script to test handling of many (e.g. 5000) views

Changed the initial allocation from
    liste->nmax = ((n - 1) / liste->incr + 1) * liste->incr,
which does not allow us to allocate lists smaller than iste->incr, to
    liste->nmax = n;

With this change, when we do "List_Create(1, N, sizeof(blah))", we
initially only allocate sizeof(blah) instead of N*sizeof(blah).

fixed memory leak introduced when I added support for curved elements

- changed "View.ArrowLocation" into "View.GlyphLocation" (this way we can
  also use this option to display the numeric values at the nodes,
  instead of displaying always at the barycenter)

- changed the numeric display of vectors (display the 3 omponents
  instead of the norm)

- allocate less memory during the initial alloc of the view lists (to
reduce the amount of memory used when loading many views with only a
few element types--about 150Mb for 4000 views)

- better accuracy when creating points with the mouse

added small warning in automatically generated opt_* files

removed limit on number of file names allowed on the command line

better help string for '-combine'

added all the missing "Combine" modes in the parser

The FLTK folks have deprecated fl_ask(), so we need to replace the calls
to fl_ask() with calls to fl_choice()

smaller lc files (%.16g -> %g)

doc 2nd order elements

- Generalized the "View" parser so that we can add new elements more easily
  (the code is *much* shorter, but unfortunately about 10-15% slower)

- Upgraded all post-pro file formats to handle curved (second order)
  elements: SL2, VL2, TL2, ST2, VT2, ... The new version number for the
  postpro files is 1.4

- Added code to automatically split the curved elements into linear
  elements when the view is created. WARNING: this is only a temporary
  solution: weshould generalize Adaptive_Post_View to handle these curved
  elements.

typos

add FAQ entry on PS "ghost triangulation"

add FAQ entry on multi-time-step views

I think Gmsh is ready (performace-wise) to use FastRedraw=0 by default

polish

new rotate script + refactored the anim script into 2 separate files

add line stippling for 2d plots

removed unused Post.Scales option

if no mesh file name is specified, use the problem name to construct one
