Message:

• Modified: Reworker IsoEngine unit to support multiple iso maps with different tile sizes.
• Modified: Changing tile size in main windows map doesn't affect other tile drawing on panel and in other windows like help window.
• Modified: Optimized tile size switching. Graphic assets needed for given tile size is prepared only once. Then switching between them is just about changing references to objects and redrawing.
• Modified: Code cleanup.
