  Fix bug in handling framework:end_tc timeouts
  Fix bug that prevents the interactive shell mode to start properly
  Fix failing multiply timetrap test case
  Minor fixes in code and test suites
  Add support for executing pre-loaded suites (e.g. modules loaded as binaries)
  Add test suite for remote loading of binary suites
  Fix error with {repeat,0} property in groups causing double iterations
  Add support for config info functions (e.g. init_per_suite/0)
  Add support for dynamic timetrap handling
  Have end_per_testcase run even after timetrap_timeout and abort_testcase
  Flush old DOWN messages in demonitor
  Add groups in test specifications
  Add new tests for test case groups and test specifications
  Improve and fix various test suites
