added support for my pid so I can test the changes:
3 events were mapped to one, this allows discerning which is which.
on my mouse there is a button with a 3 colour-led.
I can now determine in user-space which colour is visible.
this patch replaces my previous ones.
if you use an older kernel than Dec 28th 2015, use previous patch!

add support for mad catz r.a.t.5
add a file in sysfs called "mode" exposing the integer of that name.
