Control DDC/CI-capable display using python-smbus.

Small POC evolved into a full-blown interface now! Code is pretty much self-explanatory, especially in conjunction with example included in libraries main.

qddccigui.py is an example app, a PyQt4-based brightness/contrast controller. Bus ID can be provider as the first (and only) commandline argument, bus 8 is chosen otherwise. (Most probably because my primary display is accessible on that one, but not really sure ;)) Icons used in this example are courtesy of Glyphish.

You may also find ddccontrol-db and ddccontrol -p helpful when looking for control addresses.
