Tile World 2 64-bit patch

[KeyboardWielder]

"It's already on my list."

I'm getting tired of saying that, so am thinking of releasing TW 2.0.1 sometime soon with the following fixes:-

TW2-specific:-

- "Stuck Alt" after Alt+Tab on Windows 7

- "Stuck arrow key" after level completion on Linux

- Additional console window on Windows

- Possible UI color issues when using some desktop themes

- const_cast problem in code which somehow compiled with GCC 3.4.x

TW1 + TW2:-

- TWS handling in 64-bit builds

- Toggle wall initialization bug in Lynx mode

- Potentially advantageous incorrectness in mouse emulation in MS mode

- Package with CCLP2 and CCLP3 included

... which is what I intended to do one year ago. But catching up with real-life after spending a lot of time on CCLP3 and TW2 took its toll, and I never got around to it. It's been such a long time since then, that I keep thinking that now it's time enough for a TW 2.1 with larger improvements. On the other hand, it's been such a long time since then, that I should be realistic and stop sitting on easy fixes which people are asking for.

@tensorpudding, let me know if there's anything else you found that's not on the list above.

Thanks.
