profilesafe: Add values for SecureUserConfig feature/profilesafemode

Added default values for SecureUserConfig values
to soffice.ini/rc which enable the mechanism,
enable by default and set a maximum of three backups
file in packed form. Added more handy flag for easy
decision to add compressed/uncompressed.
