Previously, the buttons were only enabled with an unlocked y-axis.
Now, they can be used to adjust the ground position.

This also adjusts the settings-init process to fill in the saved
settings with setTimeout. It was trying to update the settings
dropdown before it was inserted into the document!

Buttons are now flat-looking. The view picker is now as wide as
the other elements. Presets have been moving to the menu. Settings are
padded differently. Menu buttons (just the popout menu) are now square.

This is just because it's holding non-ratio-related info now!

Forms allow for one entity to have multiple distinct sets of
views and sizes.

Entities can now be rotated. This does not affect
their height. For now, they can only be rotated by
45 degrees at a time. I will work out something nicer
later on.

Buttons/inputs/selects use the Coda font, and inputs
are more evenly sized

This can improve performance on less-powerful computers.

The font-size of the div containing each image was causing the images to start shifting
downward when their height dropped below the font-size.

This also gets rid of the groups, which were messing up the layout.
