Extend the copyright script for python and script files

[folmos-at-orange]

Description

Currently the script scripts/update_copyright.py only changes .cpp and .h files. It should also consider python and shell files

Questions/Ideas

• The comment operator depends on the extension:
  • .py, .sh : #
  • .cmd, .bat : REM
  • .h, .cpp: //
