 * fix raising of errors (refs #125)
 * fix reporting for missing environment-modules (refs #7)
 * fix function names after refactoring in framework.application (refs #125)
 * fix getting Application instance (refs #125)
 * fix default value for toolkit (refs #7)
 * improve logging (and stdout output) (refs #7 refs #57)
 * add default logFormat (so build_log testing works) (refs #7)
