Improve regex searches and file copies

[Johann-PLW]

• In the report folder, temp directory was renamed data
• Convert_plist_date_to_timezone_offset function updated
• Fix SQLite database attached in SQL queries in read-write mode
• Improve regex searches:
  • When a module uses a regex already processed by another one, the result of the previous searching operation is returned. Files are not searched again in the input source
  • Check if a file was already copied in the report folder to avoid duplicate copy operations
  • For Mac archives, __MACOSX folder is now ignored
• iTunes Backups (Manifest.db and Manifest.mbdb) use the same -itunes parameter instead of -itunes and itunes-mbdb. Duplicate code was removed.
