removed attrToString(), which wasn't being used
added node_close to make the form consistent
make the link of the node fill the node
SEMICOLONS
explicitly set <a> text black, blue/purple sucks
give nodes padding so text isn't on the borders
treemap now shows comments, up/downvotes
image backgrounds, for the hell of it

it's 2am on a sunday, this is obviously how I should be spending my time
