Add support for proxy when sharing entries

[eyJhb]

When having set up proxying for e.g. images, this works fine when initially viewing a article. However, as soon as the article is shared, the proxy is bypassed and no longer used.

This doesn't seem intended, at least not obvious when initially setting the proxy.

I couldn't find other issues related to this, so hopefully I didn't miss anything :)

This is currently the expected behavior. The media proxy is not used in the public/non-authenticated views. It has been implemented this way since the sharing feature exists (see #475). However, that could be changed, or become configurable.

Lines 212 to 216 in c3c42b0

	{{ if .user }}
	{{ noescape (proxyFilter .entry.Content) }}
	{{ else }}
	{{ noescape .entry.Content }}
	{{ end }}

I think it would be fairly nice to support that. I try to host privacy centered services, and I had somewhat expected this to be the functionality.

Could this get a feature request tag instead? And a renamed title?
