[PATCH] Improve detection of input device source type

[Thomas Jaeger <ThJaeger gmail com>]

This detection code is not 100% reliable, but it should fare much better
than the current code, which just compares the device name to a fixed
set of strings.  Many applications depend on erasers being recognized
reliably, so we start by checking for a device name containing the
substring 'eraser'.
