Subject: Move whowas containers into whowas class to avoid all cpp files
 including cmd_whowas.h to try and destroy the containers on fork exit.\nThis
 would cause a segfault when forking due to the containers destroy being
 called multiple times, but still allow the server to fork it's child and
 leave the server running.
