whoami: a pedestrian user id retriever

WHOAMI displays a long user id (LID) in the form
%time|username|domain|hostname|osarch|osname|osver|MLver

WHOAMI optionally returns various system properties including a short user id (SID), which only contains static information about the current system
programmers can easily create their own IDs or change the built-in formats, which may be a useful tag in source control

example of the short output (note: formatting will most likely be bad)
