provide a way to statically access config

[ghost]

in reference to https://github.com/fablab-wue/piTelex/commit/4e54ea91605042340cb8f4538128bbc408795b12 please consider either providing a way to access config statically or decapsulate functionality from event handler (i think the former would be prefererable.) if option is urgently required, value could be chained into event handler, which would be my least preferable option, as it would degrade readability and increase complexity. IMHO, a static instance for program configuration values would be ideal. either way i'd like some input before moving forward. apologies for the oversight, did not notice the inner class declaration.
