Added new flag t.accelerometerjoystick to love.conf (true by default.) When set to false on mobile, the device's accelerometer will not show up as a joystick even if the joystick module is loaded.

This can reduce CPU usage if you don't use the accelerometer but you don't want to disable the joystick module entirely.
