Added patch from William Shipley which allows shutdown time to be specified

in the format +hh:mm. This is in addition to the existing formats such as
hh:mm, +m, and "now".

Cleared up compiler warning in dowall which can happen if the
output message is longer than the size limit on the snprintf()
buffer. This is not a bug, a the trucation works, but using a larger
buffer avoids the warning on systems with long user/host names.
