Support SSL by default

[boncey]

Flickr will be switching off the HTTP endpoints at some point.

I see flickraw supports HTTPS but it's not the default (as far as I can tell).
Can it be made the default please?

Done in 339f142.

Some of the methods still answer with http endpoints (sometimes ?).
https://flic.kr/p/ url have an invalid certificate.
