Config file for colors, styles, exclusion

[neumond]

Currently only model exclusion list is implemented. It is a raw text file containing list of fully qualified model names (you can see possible names via -p option). There's no way to specify background colors for apps and models, assign styles for arrows: you have to do this manually in dia and it can be very boring. Possible solution is configuration file, may be YAML, with all this data you'll fill during fune-tuning diagram output.
