nathangray 0d37c8413f Add resource categories to owner / participant search results
In the sidebox menu, resource categories are returned and selectable and will show events for all resources in that category.
In the edit popup, if the category name matches the search string, all resources of that category are returned and user can select them as if they would have searched for the name of the resource.
