[BibTeX] Generate incomplete citation which includes SWHID when metadata is unavailable

Hi,

I just discovered the nice Citation button. However, it's not available with all the archived content. For example, missing from the well-known Apollo source code. :-)

I guess that's because some metadata are missing inside the repository. :-)

However, it could be still nice to be able to format the Permanent link as a BibTeX entry. For example with these fields:

    license
    date
    file
    repository
    version
    swhid

More or less, because they might not all be always available.

Or having a Citation button with an incomplete BibTeX reference ready-to-paste for the cases where the metadata is missing.

Bah a random idea when using these buttons. :-)

Cheers, simon
