Implemented the ImportEvents command line tool, which allows event
definitions to be imported. In all cases the tool will try to import all
definitions; if an error occurs, the process continues but the
transaction is rolled back. It skips existing definitions rather than
taking the risk of doing something inappropriate (e.g. deletion of
existing events).
