Importing modules was wrong in `selector`

[MarioMey]

This example:

from evdev import InputDevice
from selectors import DefaultSelector, EVENT_READ
selector = selectors.DefaultSelector()
keybd = evdev.InputDevice('/dev/input/event2')
selector.register(keybd, selectors.EVENT_READ)

To this:

from evdev import InputDevice
from selectors import DefaultSelector, EVENT_READ
selector = DefaultSelector()
keybd = InputDevice('/dev/input/event2')
selector.register(keybd, EVENT_READ)
