Added targeting flags:
-nu - No Unload
-nr - No Regular archived files.
-ns - No Spec Depot
-nS - No Shelved
-a - Archive Depot verify.
Verification of archive depots with '-A' is now supported,
though not enabled by default as archive depots are typically
in cold storage.
Also made doc tweaks, enhanced description of '-L' flag and
correcting '-h' usage.
Added warning message if an unknown depot type is encountered.
Unknown depot types are ignored, as new depot types typically
require new logic to handle.
More updates for shellcheck compliance.
