cleanup some trailing whitespaces
Update README file
getting ready for 4.4.1 release
updated AUTHORS, README and ChangeLog files for release
Final makefile adjustments and compiling instructions.
cleanup: got rid of a lot of files that are not needed for a new release lots of documentation was available in several places, old unused source files and not used graphics file were floating around in the tree. This should clean up most of it. No need to keep these files around, especially since we are using version control.
changes from H.G. Muller; version 4.3.15
