Grid updates, Remote access bug fixes and improvements

Created by: marcus-oscarsson

Hi

Grid is now stored in microns internally which makes it easier to handle zooming, consequently zooming now updates the size of the grid. There is also some more information displayed in the grid dialog, number of cells and grid dimensions.

I updated fabric to the latest version 2.2.4 since there was some issues with the version we were using. I also tried to optimize the grid drawing, we had some performance issues with large grids.

Several fixes for the remote access, most importantly giving control and file paths. Also added a sample changer status component.

Cheers, Marcus
