Remove some of the empty off-screen space around the game
Now large clickables will not affect scrolling
Now the overlay does not have a border that will make the page bigger
If there are no scroll bars, scroll back to the top (fixes the bug if you scroll when the window is small and then make the window big again)
Merge branch 'master' into fix/scrolling
Merge pull request #39 from rcatlin/fix/scrolling
