Modify the module in the master file

[abdelaziz]

For a concern of a homogeneous workflow and for a concern of a good use of the memory vive it would be preferable that the edition of the module is done on the same master file, the idea is to modify the module as a staircase or Like a curtain wall
1 - the master project becomes gray in the viewport
2- the origin of the module appears on the viewport
3- the bar of anglet becomes blue
4- a new navigation palette opens that includes the model view
