Subject: [PATCH] =?UTF-8?q?180=C2=B0=20Turn=20only=20once=20per=20button?=
 =?UTF-8?q?=20press?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Introduced state variable to only allow a 180° Turn once per button press (either mouse or keyboard). This improves the useability when binding it to a mouse key.
