In issue #662 a more readable PGN output has been requested. Usually PGN outputs are listing more than one move per line and the line width limited to 80 characters. This patch provides a method to optionally list one full move per line with aligned columns.

A context menu item "Copy with PGN header" is added to the context menu of the MoveList. The output is copied to the application clipboard.

The patch adds a lambda expression to MoveList::MoveList to copy the game's PGN header and a formatted move list to the clipboard. The move comments are omitted if the are hidden in the MoveList.

An alignment flag is introduced as method parameter to the two PgnGame::write() methods.

Resolves #662

A new menu item "Copy with PGN header" is added to the move list's context menu (right-click).

Add function to copy PGN header and a formatted move list to the clip…

…board.

The move comments are omitted if not shown in the MoveList.

Introduce an alignment flag to the two PgnGame::write() methods.
