Add some drafts for upcoming tests

Fruit as mushroom replacement
Wood crate as spin box replacement
SMC banner and logo based on new name
Fixed size and colrect's of blue gems

Made the blue gems (yellow coins before) a bit larger as per community
discussion, and fixed the collision rectangles to match their new size.
Spin box improvements

Lightened the color up, so it stands out better on most levels.
Made the spin animation smoother.
"Swatchified" the main SVG so it's easier to modify colours in future
Increased size to fill the tile better
Adjusted colrect's to fit
Updated HUD coin image to gem

So that the coin counter now shows that it's counting gems
Spinbox visual improvements

Various improvements to the look and animation of the spin crate, most
notably lightening the color so as to not make pre-existing levels look
to radically different.
