Ported over to our own private API - it's now functional under the Haiku kernel.

Browse Source 
Improved argument parsing code - you no longer have to specify each option separately.
Improved time parsing for the "-d" option: it's now possible to add a unit to the
time value ("m" or "s"), and you don't have to add a space anymore (ie. -d5 will
work, too).
Cleaned up the source file to better match our style guide, and look better overall.

Also added a comment about the usefulness of some of the options here - I think
we should remove the alert stuff again; one requester (in Roster) is really enough
for my taste.
