Idea: install udev rules with Snap package

[szszszsz]

Install udev rules from the Snap package. These are required to work for the application under Linux, however they are not installed automatically. Because of that some users can report lack of the connection, when using this distribution channel.

Installation would need to be realized either through the Snap installation script (if Snap/confinement allows), or implemented inside the application.
