Couple of progressbar fixes. Tactics game (opening reps) and HTML/js export.
Tidy up the html/js output a little.
Update our long broken javascript HTML export to scidCommunity's (with some tweaks). Progress dialog 'Stop' is still not working though. Hmmm!
german patch typo.
Hack a toggle/state feature when right-clicking the showBoard button (to show arrows on the main board).
blackLineColor is now grey50. Hard to read the numbers on mac otherwise.
Handle stockfish/lichess %eval comments.
When showing Hanishes sequential arrows on main board, show as larger size.
