Improving the Novag Citrine Interface

I have improved my Novag Citrine interface. I have added a pull-down menu to choose between playing against a PC based engine, or the on-board Citrine engine at various levels of play. The pull-down menu curently offers the strongest "Beginner" level BE1, and the eight "Average Time" levels AT1 to AT8. I have coloured the start/stop button light green when it is showing "Start Engine", and pink when it is showing "Stop Engine". This is how the window looks now:

The program now writes the options available for PC engine to the console on start-up. Here is the table for Stockfish 7:

Engine Option         Type    Default Min    Max     Var
Clear Hash            button  ''      None   None  
Contempt              spin    0       -100   100  
Hash                  spin    16      1      1048576
Minimum Thinking Time spin    20      0      5000  
Move Overhead         spin    30      0      5000  
MultiPV               spin    1       1      500  
Ponder                check   False   None   None  
Skill Level           spin    20      0      20    
Slow Mover            spin    84      10     1000  
Syzygy50MoveRule      check   True    None   None  
SyzygyPath            string   None   None    
SyzygyProbeDepth      spin    1       1      100  
SyzygyProbeLimit      spin    6       0      6    
Threads               spin    1       1      128  
UCI_Chess960          check   False   None   None  
Write Debug Log       check   False   None   None  
nodestime             spin    0       0      10000

These options can easily be changed from within Python, e.g.:

engine.setoption({'Skill Level' : 0})

This certainly works - Stockfish plays rubbish on Skill Level 0. The code can be found here. [Updated 5 July 2016.]
