New Control Scheme and Speedrun Timer

The latest version of "My Lovely Wife vs. 100 Draculas" adds two new menu items.

The "Swap Controllers" option was suggested by RealShadowCaster on the Lexaloffle BBS. You can now swap the movement and shooting control inputs - allowing you to move with the arrow keys and shoot with ESDF if that feels more comfortable.

The "Show Timer" option adds a speedrun timer, which starts after destroying the targets on the first tutorial screen, and stops when you defeat the 100th Dracula. Thanks to Protractor and Sapazu for the suggestion!
