0.3.0

• Support for Groups. Groups need to be activated on the Gateway device Control panel. A group is represented as a light device, to be able to switch it on/off, set brightness and color, regardless of which devices are in the group.
• The plugin will now poll the Tradfri devices for their state instead of relying on observing. The poll interval defaults to 30 seconds and can be changed by modifying the PollInterval attribute.
