Have About page indicate installation type

I think it might be useful to have the About page include information such as how Duplicati is being run (service or tray icon hosted server) as well as the user or system account it’s running under (if that’s possible / applicable depending on OS).


I guess we can check what entry assembly it is, and maybe use that to display how it is running. The user context can also be extracted, although it needs to be done differently on Windows and the others.
