Huge cleanup, removed old unmaintained boards/libs/archs....
Huge cleanup, removed old unmaintained boards/libs/archs. Changed from building once the lib in small archives to whole rebuilding from sources for each executable, this will allow to use build-time switchs/optimisations. /!\ Simulator broken.
