Further integrate ocgdb into Banksia to replicate SCID capabilities like Tree View, player report etc.

Hi Pham! I really like your project. I've exported my 7+ million database from Scid into it and I am very impressed and pleased with the ability to query it using SQL (and joining one database to another to do selective updates etc.). I do have difficulty re-importing the pgn file I export using ocgdb back into Scid (primarily due to Scid constraints and idiosyncrasies on ply limits, limits on number of unique records in specific fields etc.). I would love to abandon Scid and just do my database analysis using sql, but Scid has a lot of nice features like tree views, player reports, best game lists based on the current board position etc. I see that you have integrated the ability to load an ocgdb database into Banksia GUI. It would be great if that integration continued to provide more "canned" reports/views that query an ocgdb database based on the current board position being analyzed in Banksia. Kindest regards, Hugh P.s. I really appreciate all your great work!
