New artwork and TC ranges for team color-able icon bases and cursor hexes

The icon bases are meant for use with the terrain type icons and unit profile icons.
Team color-able hexes offer a flexible alternative to  single-color cursor components.
A set of color ranges specifically tailored for terrain type icons has been added to team-colors.cfg. Each color range is named after the base terrain type it corresponds to.
