Filename structure changed
Filename/ function name structure changed

File Structure
==============
File names resemble what the code does. All library routines for the
Atari DOS 2.x FMS are called '_D2x_*.*'.
All source code files and binarys using the Dos 2.x library functions
are called 'at*.*' ('atdir' for example).

Source Code structure
=====================
Function names resemble their origin. For example:
D2x_init_image(....); shows, that this function can be found
within one of the files named '_D2x_*.*'
Batch processing added. More debugging done

'-f' option enables batch processing. The file 'filename' contains a
list of path- names pointing to *.ATR image files.

Checked 12.000 *.atr files with the '-f' option to prove that atdir
works correctly. Well, there are some issues left, possibly caused by
wrong file size/ disk size formula……..

Added 'sdir' sub. Shows the directory very short. Just the filenames
and if the file is deleted. This function is more stable then 'dir'…..
