A fix for onboard to show keys and not "?" question marks in tightvncserver. Implements or emulates a basic us keyboard.

Its good enough for me but not good enough to push.

It uses PyUserInput as backend.
so for python3 for example you need
apt-get install python3-pip
pip-3.2 install PyUserInput

install on ubuntu:
# backup
cp /usr/lib/python3/dist-packages/Onboard/OnboardGtk.py /usr/lib/python3/dist-packages/Onboard/OnboardGtk.py.org
# overwrite
cp ./IOnboardGtk.py /usr/lib/python3/dist-packages/Onboard/OnboardGtk.py

known errors:
num lock is not working so no numbers via numpad
the key to the right of left shift just produces "<" always
most long press keys wont work (ö ..)
