July updateHEADmaster

Added const qualifiers is_next_to_empty_box() became visible to other files().
The size of the main window has been changed.
Checking whether the A* algorithm has been launched before starting a new game
or the same A* algorithm.
Fixed indentation in lambda expressions.
The initial node is added to open_queue without additional creation of dynamic
memory (the address of the object field is taken).
Fixed PQ_cont.erase().
IsNearEmptyBox was removed().
EqualNode moved to the Node class.
