Fix minor inconsistency in description of cipher categories

A longer while back the section ~ "Testing standard ciphers" was
renamed to "Testing cipher categories". However the internal help
didn't reflect that.

This fixes that, including an addtion to the documentation.

Note: the help still lists "-s --std, --standard" as a cmd line
switch.
