Map: Mark Tiles with Colors

[Hirnsausen]

It would be useful, if we could mark one or more tiles with different colors (inside right-click menu). Imagine we want to search different tiles for ore, or we want to claim am area with different tiles. So we would mark some number of tiles with yellow, and one or two other tiles (just an example) with brown or pink or so. These tiles remain colored until we remove them. A set of 3 or 4 colors to chose from should do the trick.
