Added missing proxy fields

[nwinkler]

When using http.get() to request a file through a proxy, the following were missing from the previous implementation:

• The http:// protocol
• The headers object indicating the target Host

These additions are based on http://stackoverflow.com/a/6781592/1228454 and work for our company proxy (MS NTLM Proxy).

The previous implementation always silently failed, it simply exited the process right after the fetching ... message.

Worked for me too :+1:

@dodo this would then resolve many issues on dependant projects: dodo/node-slug#58 keystonejs/generator-keystone#129

the symptom I'm seeing is Error: Cannot find module 'unicode/category/So'.

...The proxy server sends back a page saying "Sorry, I don't know how to get to that URL without a protocol" and this library tries to parse the error page as if it was UnicodeData.txt, so you end up with undefined.js and font-family: Tahoma, Roya, sans-serif.js in the category directory.

Does this needs any more work before merging?

This would also fix an issue I'm seeing on Circle CI:

Hi there, any news on this? This issue is pretty annoying... :)

+1 on this, it is a very annoying issue causing our travis-ci builds to fail.
