LibDraw+LibGUI: Allow changing individual colors in a Palette
Palette is now a value wrapper around a NonnullRefPtr<PaletteImpl>. A new function, set_color(ColorRole, Color) implements a simple copy-on-write mechanism so that we're sharing the PaletteImpl in the common case, but allowing you to create custom palettes if you like, by getting a GWidget's palette, modifying it, and then assigning the modified palette to the widget via GWidget::set_palette(). Use this to make PaintBrush show its palette colors once again. Fixes #943.
