OMEdit: change package saving

[Anatoly Severin]

There are 2 ways to create package with some models.
1st is to create file somepackage.mo with such structure:
package somepackage

model somemodel
end somemodel;

end somepackage;

In this variant OMEdit saves package and model correctly.

The other way is to create a folder somepackagefolder and then create a number of files in it:
package.mo :
package somepackage
end somepackage;

somemodel.mo :
model somemodel
end somemodel;

usually 2nd variant is used to create a library, but it's also useful for developing complex models.

nowadays OMEdit doesn't support saveing 2nd variant packages.

I`m opening package.mo (it opens correctly), editing model, and save it. OMEdit places all code from model(models) in package.mo but doesnt saves changes neigther in package file nor in model files.
