Feature request: Save Flickr image names and timestamps

[Flandyn]

Currently, if you download any images/albums from Flickr using gallery-dl, they will save with the filename "flickr_xxxxxxxxxx.png".

However, when downloading albums (not individual images) using Flickr's download function, rather than beginning with "flickr_", the filenames will begin with whatever the image's name is, for example "image-123_xxxxxxxxxx.png".

Also, when downloading a Flickr image using wget, it will save the proper timestamp rather than the date you downloaded the image.

Would it be possible to add an option to gallery-dl so that it can do these things? I would find it very helpful.

You can set a filename format string (example) that will get you very similar filenames to those from Flickr's album download: "{title}_{id}.{extension}"

It won't have the little image format indicator at the end (_o, _k, etc), but it wouldn't be much of a problem to make them available if you really need them.

Setting a "proper timestamp" from the Last-Modified header isn't possible as of yet.
