add shebang and exe-attribute

[KM-200]

so the .py files are run via click-to-launch in dolphin filemanager:

#!/bin/bash
rm                         /tmp/_xx
echo -e "#!/usr/bin/python3 \n# -*- coding: utf-8 -*- \n" > ./shebangPYheader
for FILE in $(find ./examples/ -maxdepth 5 -type f -name "*.py"); do
  chmod +x $FILE
  cat ./shebangPYheader >> /tmp/_xx ;  cat $FILE >> /tmp/_xx ;  cat /tmp/_xx  > $FILE
  rm                       /tmp/_xx
done

now the example files can be clicked and run nicely ! Even those containing "\n" which will not be converted to a real linefeed, which would have been breaking some programs in alternate scripting.

here is a second way to do the same thing:
