Added saved curve settings in Color Management

[schroef]

Always nice to use this addon. I hardly know what is Blender Vanilla and what is from this addon. Remember when i started using 2.80 that i was missing it so i started porting it, someone beat me to it. Though i still prefer the older method of the missing links. Think im going to revert that again. Anyways...

I was noticing that curves didnt do anything when settings are saved. I remembered an addon where i also implemented a curve so i knew the data of those points can be reached. Then started to thinker with the AddPresetBase function/operator.

I know got it working, it saves every curve which has been edited, 4 that is C,R,G,B it now also saves all the other settings which were missing.

ill make a fork and do a pull request. I tried to keep the code as clean as i could. Im no pro dev, so perhaps lots of my code can be simplified, but it works thats good for me https://user-images.githubusercontent.com/6923008/113667093-4bff4b80-967e-11eb-9fe3-e49b94b73b7d.mp4

This is what a file looked prior

import bpy
scene = bpy.context.scene

scene.view_settings.view_transform = 'Filmic'
scene.display_settings.display_device = 'sRGB'
scene.view_settings.exposure = 0.0
scene.view_settings.gamma = 1.0
scene.view_settings.look = 'Low Contrast'
scene.view_settings.use_curve_mapping = True
scene.sequencer_colorspace_settings.name = 'sRGB'

This is how it looks now with saved curves settings. I could perhaps better use a DICT but im not really at home with those. Ill try to do some more research, could save a lot of lines
