Update via external script

Concept

• Update copies update Script
• Session is established via nonce etc
• In the admin new instance (new tab / iframe) the script is then executed
• first, use a try run to check if file system has changes (if yes, update should not be executed -> display an attention)
• create a system backup before update starts
  • packages, etc + database

Workarounds etc. can be displayed here, too. The updater can check if system command is available etc.
