Removing updownarrows.png from the root directory...
Changed radiobutton.png to be a bit smaller/prettier
Removing all the resources in /res/ that aren't/won't ever be used.
Put some error handling in ved/webutils

Now you can check if a request returned an error by checking if
postToUrl or getFromUrl returned a number instead of a string.
Added smallvertarrows.png, for use in edit mode.
Updating static.html
Added a play button for use on the start menu,
and a save button for use in edit mode
Fixing up the level editor and start menu.

The level editor is now feature complete inside the
game frame, and makes no use of DOM elements.

Still need to make the level editor notify when a save is
successful.
