Will Norris 0370572130 change how content-type enforcement is handled
If no content types are specified, then accept all responses, regardless
of content type (this is the behavior imageproxy has historically had).
Change default value for the contentTypes flag to be "image/*", so that
the new default when running cmd/imageproxy is that only images will be
proxied.  The old default behavior can be achieved by passing an empty
string for the contentTypes flag:

    imageproxy -contentTypes ""

Do not send the "XCTO: nosniff" header, since all documentation that I
can find still says that it can cause problems when served with images.
If it's effectively a noop when an explicit content-type is specified in
the response, then this shouldn't actually matter for us either way.
But in the absence of certainty, I'd rather err on the side of following
the spec.

Also add documentation for the new functionality.

Fixes #141
