Change the visualization icons to read only (view) if viewer user access

[khalil]

You can add this class to any visualization element that still needs to be clickable. But this solution will only block the UI. The user still can write to objects. For example by opening the browser console and executing grp.write() from there.
There's no solution to fully block writing at the moment. It's only possible to provide a list of objects that the user can read and write in Advanced tab of user properties in User access.
