Much better :D
Make sure that this regex doesn't allow other mis-sized images to sneak past
lint. I'd try messing up another image's dimensions and see what the error is in
that case.

For comparison, lint prints out a single IconDensities warning that contains a
list of all images that are missing in some density, so the regex I added for
IconDensities very specifically begins with ": " and ends with "$" to ensure
that if other images are missing densities, they won't match that regex.
