adds the client example for idle-inhibit
Adds a client example for the idle-inhibit-unsable-v1 protocol. The client creates a surface and requests an idle inhibitor. On pointer BTN_LEFT the inhibitor is destroyed if it exists, or recreated if it was destroyed before. The surfaces colour is based on the idle-inhibit state. Green if an inhibitor exists, yellow if it does not.
