Miscellaneous improvements * Altered function names in roundup.config to bE NeAtEr rather_than_ugly; * Created some extra roundup.config exceptions to let people know what's going on; * Modified instance_config.py to use those exceptions, so that syntax errors or other exceptions did *not* trigger the same behavior as import while in the templates/ directory. * Modified roundup.cgi to use the same neater function names, plus did some minor cleanup.
