Fallback/default configuration

[BlackmanCC]

I would like to use abaplint checks integrated in SCI/ATC, but I do not like to give a configuration for each package.
Instead I would like to use a fallback configuration e.g. of package $ABAPLINT_FALLBACK_CONFIG (empty package or reference package) if there is no configuration for package found.
I implemented this by post-exit enhancement for method FIND_FROM_PACKAGE in ZCL_ABAPLINT_CONFIGURATION, but I think this would be useful for other people.
