currently there needs to be a config json so makers can appear properly.
(bug: markers appear incorrectly if you try to setup again, must be the offset from the red border)
- added "done" button during marker or region selection
-added openarrowmarker in region selection dialog
-made bobrustpalette receive a screenshot of the color area, split it into 4 by 16 grid and map the coords relative to screen. getSizeButton is changed to work with the brush size limit of 100
-palette generator is unused now.
- made the coordinate record in its own file
-made circleCache load circle_config.json and create one with defaults if it doesn't exist. made for easier testing.
- added config file related functions to ApplicationWindow.
Thanks for the developer for explaining and helping me make this work.
