v1.6.0

• plane configuration errors now do not crash the app but pop up the error. (Now good error messages provided by glassesTools update)
• add button to deploy default config of glassesvalidator planes, asks if want to overwrite
• ensures popups cannot be dismissed by key press when the action is not possible (e.g. create a plane with invalid name)
• GUI improvements: detect marker GUI cannot interrupt the process (done button removed, close does nothing), video maker GUIs have a stop button instead of a done button (to better reflect that pressing it stops the video generation at that point)
• individual markers can now be marked as "detect only", in which case their size is not required (their pose will not be recovered)
• renamed video_ settings to mapped_video_ settings, introduced new settings for overlay_video_ to control look of gaze marker on gaze overlay videos
• Generalized auto code trials to auto code episodes: can now also auto code ET sync and validation episode start and end
• Updated readme and examples to match current functionality and GUI looks
• various small fixes and enhancements
