Add Fade in / Fade out #13

The EGA version fades in and out when entering a level. The CGA version doesn't have this, and therefore the Tandy version also lacks this feature.

Super easy, barely an inconvenience. The code is already there, it's the same for Tandy as for EGA http://www.ctyme.com/intr/rb-0116.htm

This doesn't work in MCGA mode, though.

It's really slow in PCem.

I now change the palette in the Tandy version by using the registers instead of an interrupt.
