Title: Added spaces to authorization signature.

There was problem with 500px API, which couldn't parse auth headers with no spaces between elements.

node-oauth header:
```
authorization: 'OAuth oauth_callback="...",oauth_consumer_key="...",oauth_nonce="...",oauth_signature_method="...",oauth_timestamp="...",oauth_version="...",oauth_signature="..."'
```

What 500px server expecting:
```
authorization: 'OAuth oauth_callback="...", oauth_consumer_key="...", oauth_nonce="...", oauth_signature_method="...", oauth_timestamp="...", oauth_version="...", oauth_signature="..."'
```
