Changed file type, removing '+k' file type modifier.
Reason: The +k file type modifier is disallowed in SDP scripts, as it does not translate properly during fetch/clone operations across Helix Core servers (or into Git repos).
Introduced new handcrafted $version value to replace mk_ver_str(). The $version value must be manually updated when the script changes (as is typical with other SDP scripts).
Testing note: As changed, this passes a 'perl -c' compile check but I don't have a test environment for this script. Any testing support would be helpful.
