- Couldn't make the recent changes in tasks from master branch work, so:
- Added gzclient to the command for gazebo tiltedhex and gazebo kill tasks
- Also used the desired presentation for the gazebo tiltedhex task
- added gazebo VTOL tailsitter debug target
- improved jmavsim debug target and helper tasks to work properly (build and launch directly instead of through the jmavsim_run.sh script)
- improved output console handling for helper tasks (eg gazebo and jmavsim build and run, followed by cleanup after debug)
- added miniterm.py as a task
