Allow minimap colour options to be set with hex codes and used in WebTiles.

This changes the default WebTiles minimap colours to match local tiles.
To get the previous default values use:

tile_floor_col = #a9a9a9
tile_door_col = #a52a2a
tile_item_col = #008000
tile_friendly_col = #ee9090
tile_peaceful_col = #ee9090
tile_plant_col = #006400
tile_upstairs_col = #0000ff
tile_downstairs_col = #ff00ff
tile_excl_centre_col = #00008b
tile_excluded_col = #008b8b
