Now automagically setting all Config.pm config options in database config table when set-db-config.sh is called.

Changed run-api-command.pl to no longer use PB_PATH and pblib.cfg (only needed for CGI) -- just set PERL5LIB and PB_DEV_VERSION

Fixed export_to_bash and export_to_tcsh to no longer output non-scalars (e.g. BEGIN, import, etc)
canonicalized PB_REST_* and PB_DOJO_* and made PBREST_* and DOJO_* deprecated.
