[add] bunch of classes to handle color calib stuff independantly

may be overkill. cleanup later.
[add] color selection (pops up window (debugging)) - WIP
[add] show color selected (hex and color) in menu
[add] support for left/right hue and color (still not saving RGB)
[fix] segfault when clicking hue without selected image
[fix] color calibration schema names
[fix] cleanup, rm debug logs
[add] selection working. not nice, but working.
[fix] use unique_ptr rather than auto_ptr (deprecated)
[fix] camera calibration widget alignment
[fix] change method to checkbox for auto color calibration

i'll add the combobox mapper later
