Workaround for non-working fltk-config

See merge request !252

fltk-config is a bash script and on windows, if there's no bash environment
FLTK_VERSION will be empty and result in a CMake error. This fixes it
by quoting the version

- remove intrusive alglib stuff in MeshOptimizer, HighOrderMeshOptimizer and MeshQualityOptimizer to enable easy swap of algo

- enable system BGFS and MathEx
- use libmedC instead of libmed
- change system mmg3d and ANN lib names

(and thus not for extruded meshes)

- add reading of labels and colors from IGES files

full pass on the documentation to clarify general concepts, introduce the API and mention the new algorithms (including parallel features)

Allow installing gmsh.py into site-packages

See merge request !251

To do this, use find_library to find the gmsh shared library

make Plugin(MeshVolume) a post-processing plugin, so that it can return the value in a post-processing view

make it clear that MSH1 and MSH2 are legacy formats + explicitely state the tags should be strictly positive

Currently only store topological info; affine transformation could be added later.
