adds small style reset for legacy launcher #47
Added display:block and max-width:725px;.

The display:block directive helps slightly when debugging, as then the inspector understands the display mode.

The max-width makes sure the gadget doesn’t stretch too wide, as some gadgets depend on the old width of the player.
