ColorPicker UX improvements

- Tabs and MenuButton for mode selection and enabling/disabling colorized sliders
- MenuButton for shape selection with new icon for each shape
- Drag and drop functionality for presets to arrange order
- A chronological list of recently selected presets which are global for the editor
- Presets are now highlighted as being active or inactive
- Thicker sliders for easy targeting
- `grabber_offset` theme constant for Slider
- Uncolorized sliders
