[MapProxy] URL with @ symbol in mapproxy.yaml

[Ben Field]

When defining a tile source in mapproxy.yaml that has an @ in the URL
parameter, it's effectively hosing everything preceding it.

For example, if the URL is defined like this:

url: http://localhost/tiles/%(tms_path)s/whatever at 2x.png


MapProxy will generate the following error:

No response from URL "http://2x.png": Name or service not known


I tried escaping it, but that didn't work.  Is this a bug or is there some
way to use the @ symbol in the URL?  This issue didn't exist in MapProxy
v1.9.0.
