LI: Add a module mainly to be able to (re)initialize Log::Log4perl object.
CC: Pass wait time via &at_cadc to use with commit 5400fe0b7215.

REQUIRES UPDATE TO EXISTING CODE as the wait time is now the second positional
parameter not the first prefix element to search for.
LS: Don't import &carp. Pass options as hash to &make_logfile to control name.

Update pod. Fix spellings.
