several bugfixes

Bugfix in Segmentation

data/brand.png added

reworking of simulated raman interface to work with smaller data
ramancontrol now works with a config file to switch interfaces and default path

Furthermore, seedpoints are drawn according their unique size. Also, SeedDeletePoints override and delete areas in sure_bg (that actually makes more sense and is useful, Julia said)

Pullrequest from Josef to allow recreation of fullimage by deletion and robustness changes in segmentation.py

Initial commit of current project status. Some modification will be needed before this will work without manual adaptations…
