Previously remapd would trigger whenever a USB device was attached. This patch changes that to only trigger the script when the output of `xinput --list` changes. This has the added bonus of making the script posix compliant.
I found a much better way of doing this, without a potentially too short sleep. This script waits for an input to be added, and then waits for a usb device to be bound. The remaps script can be run as soon as the USB device is bound. These changes should improve the reliability of the script and maybe even decrease latency.
