When creating divisional awards using the generic prize template, obey config option to filter divisions by category
When managing jdivs, obey config option to filter divisions by category
Add an option to the jdivs (at the bottom) to completely whipe out all jdivs so they can be recreated (eg if age categories / divisions are deleted or changed, or if ones were created that shouldnt have been due to the filter divisions by category not being obeyed
