VSE: Add color tags to strips

This patch adds color tags to VSE strips, an overlay option to toggle the colors
on and off, a section in the theme settings to define the 9 possible colors and
two ways of changing the color tag through the UI. You can change the color
through the right-click context menu, or in the strip side panel next to the
strip name.

Color tags are defined in user preferences and they can be disabled in overlay
settings.
