Fixing a bug causing the "new" map option to lead to
"404 Map not found"
Fixing ved.gfx.Font.writeCentered() and making Game.draw() use
it for the title again.
Fixing item physics a litte bit
Added a simple ending screen that shows the score and a button
to back to the main menu. Also added a button to go back to the
main menu in the pause screen.

Disabled the timer in edit mode, so you can edit as long as you
want without going to the ending screen.

Made game.getlevellist() ignore "mapnotfound"

Moved the drawing of the large image for carried items into
game.drawItems().
