* Initial refactor of add_job_window

* Improved project naming and fixed Blender engine issue

* Improve time representation in main window

* Cleanup Blender job creation

* Send resolution / fps data in job submission

* More window improvements

* EngineManager renaming and refactoring

* FFMPEG path fixes for ffprobe

* More backend refactoring / improvements

* Performance improvements / API refactoring

* Show current job count in add window UI before submission

* Move some UI update code out of background thread

* Move some main window UI update code out of background thread
