Add a show/hide checkbox for hidden categories when creating/editing a report
When creating or editing a report, there should be a checkbox added to the Categories tab for "Include hidden categories".
The version 7.6 release added the much-requested functionality of allowing users to hide categories we no longer use and don't want to see in Category menus. However, when you create or edit a report, the Categories tab continues to show all categories, including those which are hidden. This is necessary if creating or editing a report for past time periods when now-hidden categories might have been used, but it is a lot of clutter to wade through when you're not needing to see those hidden categories from the past.

This Idea is to add a similar "Include hidden categories" checkbox to the Categories tab, so users have the option to hide all the categories they have marked as hidden when scrolling through a categories list to edit a report.
