New Behavior

New mode called shuttlewebhid is added to the Prompter View, in which a Contour ShuttleXpress (Multimedia Controller Xpress) can be used to control the prompter through web browser's WebHID API.
In this mode, when opening the Prompter View for the first time, it is necessary to press the Connect to Contour Shuttle button in the top left corner of the screen, select the device, and press Connect.
Input mapping is predefined and shown in the image added to the documentation. Further contributions making it more customizable are welcome, should anyone need it.
