Settings UI use OpenPype styles

[iLLiCiTiT]

Goal

Setting UI should use OpenPype styles instead of having it's own.

Changes

• local settings and studio settings use openpype's stylesheet
• most of settings stylesheet copied to openpype stylesheet
  • not all are same
• most of buttons in settings have real image instead of using characters
  • their size is based on font size
• use new checkbox which has size defined by font size
  • few fixes in new checkbox

Note

If anything is so different that is' bad tell me in comments.

I made a small comparison screen and have some comments

• +- buttons are a bit too heavy and prominent. If possible we should make them a bit lighter or possibly smaller so they don't - should as much
• list arrows are very imbalanced as well. heavy and the actual arrows are not centered to the circles.
• What's up with the gradient on checkbox hover :)? flat colours everywhere and a rogue gradient suddenly. Let's go with the same principle as elsewhere with slight colour shift on hover pls.
• darken the section headers a bit. They are practically white now compared to before. Better contrast, but a bit too much and it market hover highlight practically inverted (darker on highlight)
