Splitting up the message keys into package_key and message_key in the datamodel, adding a message key table, changing format of catalog files to be xml based, cleaning up tcl API and its documentation, adding acs-automated-testing tests that test some catalog and message TCL procs
adding the format proc to allow variables to be interpolated into catalog messages, updating documentation for the lookup procs, simplifying the lookup proc greatly, not attempting anything smart if lookup fails for now
