A-05. Source code for SETPWD.NLM and BURGLAR.NLM

Included here for the curious, these sources along with their Makefiles
can be found in the "official" ZIP distributions. Note that only Watcom's
compiler does the linking properly on NLMs, so you'll need it to compile
things properly (assuming your modifying things). The ZIPs contain
pre-compiled versions of the code listed below.
