This PR is the client side equivalent to daiquiri!838 (merged)

Here is the result

• The "main" state is displayed as before
• An extra badge shows the amount of "hidden" state
• The tooltip displays the details
• The custom states are supported
• HardwareState now supports a text description displayed as tooltip
• HardwareMultiState fall back to HardwareState when a single state have to be displayed, in order to have a shorter tooltip
