Subsystems of the BBS API to be initialised.
Different modules have different needs. In most cases, all of the API will have to be initialised, especially for interactive modules. However, non-interactive, pre-login or other unusual requirements may call for only a few of the subsystems to be initialised at a time (the bbslogin subsystem does this, for example).Unless you really know what you're doing, always initialise everything! Too many things rely on too many other things, and the breakage would be significant.
