Theming support for rat-salsa

This splits themes in two parts,

• Palette This defines a color palette. It contains a rainbow-table,
  explicit primary, secondary colors and light/bright/dark/black text-colors.

  Plus it contains a list of aliases for semantic colors. e.g.: "label-fg", "focus", "select", "container-base" These point to specific colors in the palette and can be used to create the actual theme composition.

• SalsaTheme Takes a palette and creates Styles.

  And it creates concrete xxStyle structs to configure specific rat-widgets. It can also store yyStyle structs for your own widgets.

Extras

There is pal-edit a visual editor for palettes. It can create the .rs palettes and has its own storage format too. And, it can be configured to use extra aliases needed by your application.

Application specific palettes.

It's not too complicated, I just had no time to make an example yet. Mostly it boils down to mapping a theme-name to a SalsaTheme+Palette.

Loadable palettes.

It's doable. The .pal files are sufficient to create a Palette, but it's not implemented yet.
