[Gmsh] combine two different msh-file in one window

[Christophe Geuzaine]

Hi Andrey,

If your results are obtained on the same mesh, just "File->Open" the 
mesh, then "File->Merge" the two post-processing datasets. (Or, if you 
saved the datasets along the mesh in a single .msh file, just "File->Open").

If your results are obtained on two separate meshes, just "File->Open" 
the first mesh, "File->Merge" the first dataset; then "File->Open" the 
second mesh, followed by "File->Merge" with the second dataset.
(If the results are stored along with the mesh, just "File->Open" each one.)

File->Open creates a new model; File->Merge merges data into the current 
model.

By default, Gmsh only shows the current model. To show more use e.g. 
Tools->Visibility->Tree Browser.
