Added support for Flickr API authentication and also added FLICKR_SETS_INCLUDE

[allanscullion]

The standard flickrapi code will only pull down 10 photo sets and the photos included in those sets seem restricted. I have added code to handle standard Flickr API authentication. All you have to do is include the API Secret in the settings. You get a one time authentication web page. You are then prompted to press ENTER to continue.

I have also added a FLICKR_SETS_INCLUDE setting. This take precedence over the EXCLUDE counterpart and allows the user to choose the photo sets they want to include.

Hi allan,

Thanks a lot for your pull request.
I have worked a while ago on a branch handling auth to generate private pages for my private photos.
You can see my work on the auth branch (it was not online before because i didn't totally finish it... and kind of forgot it :/)

Maybe you could rebase your work on this branch, i would merge everything in master then.

Hi,

It looks like in the main, your changes in the auth branch cover the OAuth authentication changes that I made. The only missing part is the code to handle FLICKR_SETS_INCLUDE. When I get some time, I will test out the auth branch and rebase the changes as advised.

Thanks for the great work btw ;)

Cheers
Allan
