Add popup for IA permalink

[foundscapes]

I Wish...
we still saw a permalink pop-up in Save after uploading media to the internet archive.

I did some research into this already, thinking I would put it in the settings page:

The archival URLs for the uploads mention simply using an identifier for the URL.

I believe identifier can simply be the folder/file name we generate for the upload.

I would suggest a simple system browser link to the downloads page for a particular uploaded item (https://archive.org/download/< identifier >/< filename >)

And a link to the user on the settings page: (https://archive.org/details/@ryan_jennings517)

Scope Creep

I would suggest using a unique identfier for application as well as the user.

Right now I believe the identifier is a timestamped folder but makes it difficult to track and could be the cause of unnecessary uploads. (see #599)

@foundscapes Needs UX, but I would just put a link in the settings page. Was unable to find a previous implementation

@foundscapes @purvi-ranawat IA cannot be logged into since the hack. They are maintaining a readonly service atm. We should probably disable it or hide it as an option.
