Improve display of automatically found file links in editor

[tobiasdiez]

Triggered by a question in the forum and a few other related questions lately. A lot of users seem to be irritated that JabRef display files although they are not linked. Thus we should improve the UI to make this feature self-explanatory. I suggest to:

• Set the description of automatically found files to be "(auto)" or "(automatically found)".
• Change the font color of automatically found files to be grayish

This issue has been inactive for half a year. Since JabRef is constantly evolving this issue may not be relevant any longer and it will be closed in two weeks if no further activity occurs.

As part of an effort to ensure that the JabRef team is focusing on important and valid issues, we would like to ask if you could update the issue if it still persists. This could be in the following form:

• If there has been a longer discussion, add a short summary of the most important points as a new comment (if not yet existing).
• Provide further steps or information on how to reproduce this issue.
• Upvote the initial post if you like to see it implemented soon. Votes are not the only metric that we use to determine the requests that are implemented, however, they do factor into our decision-making process.
• If all information is provided and still up-to-date, then just add a short comment that the issue is still relevant.

Thank you for your contribution!

Hi we are a group of five university students (@davyie, @KallePettersson, @LukasGutenberg and @martinfalke) who would like to work on this issue as part of the course DD2480 Software Engineering Fundamentals at KTH Royal Institute of Technology. Is there anything in particular we should know about?
