Adding ini-files of other sensors & Python example

All those files came via email from Morgan, our Aptina representative.
The GDX.ini is the original version from their archive, it will evolve
in a script to capture exposures with a defined exposure time, so we can
actually (programmatically) use the sensors.
Getting exposures programmatically (from DevWare)

With some help from different .ini-files I managed to get images with
different exposures from a Python script running in DevWare.
