• Changed/broken/improved the DBUS API with best practice naming (object path now prefixed with /com/kevinbader/pwmd) and standard error handling instead of using tuples.
• A new CLI parameter allows to select either the user/session bus or the system bus, with the system bus set as default.
• Add DBUS policy file needed to connect to the system bus.
• Be more liberal when reading files by triming off any newline characters.
