Marco 212a54612c Implement moves by tapping the squares
This adds an option to dragging-and-dropping which is slightly hard on
smaller screens.

Fix promotions when tapping and fix handling of subsequently tapping two pieces of your color

Cancel tap if a drag is started (tapped square will not stay red in case a drag is started)

Change url strategy back to the hashtag thing

Change version

Fix bug that would not allow a piece move if you tried to take an opponents piece.

Fix the coloring of the last move after an invalid move was played.
