Andrew Kaster f4773b0c36 Userland: Convert bitmap resource loads to load from resource URIs
Any bitmap load of the style load_from_file("/res/foo") has been
converted to the new pattern load_from_uri("resource://foo").

This will allow for porting more apps to non-serenity targets, as well
as add some flexibility if we want to experiment with other resource
storage formats in the future.
