Warning: for large meshes you still want to disable this, as performance can be much degraded

* set Solver.AutoMesh to "2" by default: this is the expected default behavior for new users.

  Warning: this means that on startup, when loading a .pro file, the model will always be remeshed. Just set this value back to 1 in your geo file to restore the previous bahavior, i.e., using the mesh on disk if available. Again, You probably want to do this for large models.

  PS : still need to clarify the autoMesh GUI.
