Better error checking (unexpected results running with no/unknown parameters)

• $ checksums.sh -help

/usr/bin/basename: illegal option -- h
usage: basename string [suffix]
       basename [-a] [-s suffix] string [...]
mdls: unrecognized option `-help'
/usr/bin/stat: illegal option -- h
usage: stat [-FlLnqrsx] [-f format] [-t timefmt] [file ...]
(standard_in) 1: parse error

• checksums.sh --help

/usr/bin/basename: illegal option -- -
usage: basename string [suffix]
       basename [-a] [-s suffix] string [...]

• checksums.sh (no parameter)

Thanks for the input. Checksums will (hopefully sooner than later) be completely reworked into a Platypus application (with CLI-support via symlink into /usr/local/bin) including user preferences via Pashua, sfv support, checksum file support etc. That version will definitely be better at checking for errors.
