xf86-input-joystick version 1.6.1-2

After updating to 1.6.1-2 , my joystick was sending keyboard and mouse events, making the system unusable.
I removed the joystick temporarily, then checked what had happened.
it turned out my edited 50-joystick.conf had been overwritten by the default file from the new package.
I've re-edited 50-joystick.conf so the joystick no longer sends keyboard/mouse events.

The whole point of installing this driver is to use the joystick as mouse. If you don't want to have it configured as mouse, don't install the driver.

I have tested joystick with and without the xf86-input-joystick driver and found it does much more then just enable use of the joystick as mouse.
With xf86-input-joystick the joystick has deadzones that make using it much easier.
Also not all buttons (especially hat switches) are detected without xf86-input-joystick installed.

Maybe /etc/X11/xorg.conf.d/50-joystick.conf could be added to the backup array in the PKGBUILD.
If i understand things correctly, then xf86-input-joystick will not overwrite MY 50-joystick.conf but instead create a .pacnew file.
