simpler tetgen integration by Jozef Vesely

generalized the solver interface to allow permanent listening on a
socket for whoever wants to connect (gmsh -listen)

the polling should also be less CPU hungry in this new version

next step is to add new commands to the protocol so that solvers can
directly transmit data to merge (geometry, mesh, etc.) in addition to
messages and filenames

- new option to choose the mesh element labels (element number, elementary
  entity number, physical entity number or partition number)

doc trsf surf orientation option

finer control of time/timestep display

compile tetgen by default so we get feedback on machine-specific problems

New plugin to compute the modulus and the phase of a complex-valued field
in-place, in one simple step. One could already do this with Plugin(Evaluate),
but it was a little bit cumbersome.

Removed the last bits of the "Discrete Surface/Line" stuff.

Gmsh can now simply read a .msh file, and use it as the boundary mesh
of a 3D mesh. For an example on how to do this, cf.
demos/sphere-discrete.geo.

This complements nicely the STL remeshing stuff: Gmsh can now
for example very easily be used to extrude surface meshes that
come from other tools.

reorder

fixed full-quadrangle recombine algo:

- run globally, not for each surface
- assign entities to elements
- split line meshes
- correctly re-tag vertices as 1st order
- plug memory leaks

fixed small bug when drawing the boundary of a prism for a time step > 1

replaced ExportLCField with ExportMeshStatistics (lc + gamma, eta, rho + elem num)

optimize 2d iso plots with vertex arrays

2 big optimizations for meshes that contain a lot of line elements:

- speed up Read_Mesh (by introducing temp tree in curves)
- use vertex arrays for lines in mesh drawing code

removed remaining Discrete Line/Surface stuff

add entries about Visibility, Clipping and Transparency
