Adding big item images, CC-BY Justin Chan
Adding layer images for use in the editor
Adding small radio button images.
Many changes, I'm  a failure at Git
Fixing a bug allowing VOLATILE_FLAG items to be picked up if
they were the only object close enoug to be grabbed.
Lowering the draw position of the big item icon at the bottom of
the screen.
Implementing one version of "mini-sets", allowing a single tile
"type" to be placed but be drawn based on its surroundings so
tiles can flow together automatically.

Also made the background and foreground layers a bit darker or
lighter. Currently the method of lightening and darkening is dumb,
and needs to be improved.
Adding logs and an example "miniset".
Adding ved.gfx.Image.prototype.loadFromCanvas(), to create
an Image object from a canvas, instead of a DOM image.
