Update existing query when saving query on existing page

[tomudding]

Two options:

1. Modify the "save"-button to update an existing query (output query name to name field)
2. Add a separate "update" button to update query. The "save"-button will create a new query.

I prefer option 1.

I should add that is already possible to update an existing query if the name is the same. So the name of the current query should be added to the name field to make it easier to update a query.
