PixelPaint: Add loading and saving of color palettes

Browse source 
Color palettes can now be stored in and read from files. The default
palette will be read from `/res/color-palettes/default.palette`
instead of being hard-coded in PaletteWidget.

The file format is one color per line, in any format that can be
understood by `Gfx::Color::from_string`.
