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.
cleaned up remaining SQL statements using text columns instead of column
indexes with the ResultSet; fleshed out specifics in the TODO for
SIG administration
