Reworked the sidebox implementation to depend less on the database and more

Browse Source 
on XML config files...the implementation should now be much more customizable
and less klunky.  Added a provision for implementing "generic" (JSP-driven)
sideboxes.  Implemented the sidebox configure button on the front page
(finally!).  Implemented a random password generator class which will be used
in a future implementation of reminder-driven automatic forgotten-password
changing.  Fixed some minor funnies in SIG menu generation.
