Lode Runner revisited.

Tonight I revisited my Coco3 port of Lode Runner, bringing the build mechanism into line with Knight Lore. Again, this means a single build for cart/disk and I also added a splash screen to the game code rather than patching from a BASIC loader. On the down side, mono and colour variants are now different builds and different images - but the pros outweigh the cons.

I still need to fix some very minor issues, all introduced with the new build mechanism, and then I'll release the latest beta demo; I fixed the GAME OVER graphics in the monochrome build many many months ago.

I should probably get the cart designed and built once Knight Lore is complete so I can actually release the full game, before starting on the next port! ;) After all, no point developing it and have it sit on my hard disk unable to be enjoyed by anyone else, especially since Lode Runner is such an awesome game!
