read.py now deprecates test.py
I went with optparse rather than argparse to support Python <2.7.
Switching to argparse later should not be that hard.
Configurations still need to be extended with, among other things:
* Name for the device
- Added all event constants except for (FF_)
- Added InputDevice class.
- Cleaned up linux_input a bit
- list of events per event class is now a dictionary
