MicroEMACS 1.8 for Atari ST

MicroEMACS 1.8 from Mark Willians C 3.09 (ATARI ST)
---------------------------------------------------

This is a recompilation of ME taken from MWC 3.09. The original
version didn't account for future screen modes and therefore didn't
provide full screen editing on the Atari TT.

I added a simple fix to astopen() (in "atari.c") which gets the text
screen max columns/rows from LINEA variables.

I also removed the function setlines() which was hardcoded for 640x0400
monochrome mode.

The original source is also provided.

Compiled with MWC 3.09 which is available via various sites as of 2020.
