bugfixes and readme

* generating uuid with uuid_generate
--> may cause issues with http transfer of uuid
Makefile and udev rule

* needs to call a script
* current rule does not work
script to start inputserver on usb pad connect
fixed script call and changed device id

* script is now called correct when a usb device is connected
* device id consists now of HOSTID_DEVICEID
* reconnection of device maintains DEVICEID since it is derived from USB topology
