Gtk UI: full color scheme support

 * implemented by exporting the most important Scintilla STYLEs
   as CSS variables and defining named widgets for the main UI
   components.
 * ~/.teco_css will then apply the Scintilla styles to the
   Gtk UI.
   This file is also for additional tweaks, e.g. enabling
   translucency.
 * A fallback.css is provided which does just that and is able
   to apply the terminal.tes and solarized.tes color schemes.
 * Other important aspects of theming like font sizes and names
   have not yet been dealt with.
   (We may want to apply the corresponding Scintilla settings
   to some widgets...)
