Singen68k, Version 1.2

Here is my 14 byte sine-table generator. 
As far as I am aware this is the smallest sine generator out there for the 68000.
May require a few additional bytes on those systems where there is no free zero and/or bss register at startup.

This version includes another small size optimisation as well as example code for
a few new platforms like the Sharp X68000 and Sinclair QL.

There is example code for the following platforms:
- Atari ST(e)
- Amiga OCS
- Sharp X68000
- Sinclair QL
- Bonus: 10 byte zig-zag routine
