Confluence database improvements

Requests for improvement:

1. We need better filtering (or querying) with Boolean operators and nesting to be able to create more useful views, instead of just "Match All filters" and "Match Any filter"
2. We need better sorting with nesting (sort by X, then Y)
3. In the "Board" view, need to be able to group by "Entry link" fields
4. In the "Board" view, need to be able to group by Tag fields with multiple values
5. In the "Board" view, need to be able to hide some groups by filtering, i.e. only show boards for a subset of the values in the chosen "Group by" field.
6. In the Embed database macro, we need to be able to not show the database name as a headline. We want to use the headline to describe what the view is showing.
7. In the Embed database macro, we need to be able to disable editing of the database from within the view.
