* Expose `CMAKE_BUILD_TYPE` to cmake gui (for single configuration generators)
* Use generator expressions to get debug vs release mode
* Fix mac app icon
* Added property for aspect ratio
* Working version with aspect ratio slider controlling the FOV, and also gets updated by a window resize.
* Created horizontal fov property / GUI control that preserves aspect ratio by adjusting vertical fov to match, and updates with window resizing.
* Added separate directory for session recording files
* Changed recording & playback paths to use RECORDINGS dir and prevent absolute or relative paths in filename.
* Updated .gitignore so that recordings directory is ignored.
* Added session recording topic for synchronization of rec/play state with web gui.
* Added support to sessionRecording for providing a list of available playback files to web GUI.
