Make External Changes Resolver dialog scrollable

[koppor]

The box in the "External Changes Resolver" should be scrollable

1. Create a new library with a few groups and assign some entries to them
2. Outside of JabRef, open the bib file in a text editor, scroll down to the end of JabRef and modify the group structure, e.g., change the group name or add new group by copy and paste
3. Wait for the dialog "This library has been modified by another program"
4. Click on Review Changes
5. See the metadata like in the screenshot

Hey, @sambujangfofana and I are students from the University of Michigan. We are currently working on a project wherein we have to contribute to a Github repository(https://eecs481.org/hw6.html). We are pretty interested in this issue and would want to work on it. We hope to submit a pull request this week. Could we be assigned this issue?

As a general advice for newcomers: check out Contributing for a start. Also, guidelines for setting up a local workspace is worth having a look at.

Feel free to ask here at GitHub, if you have any issue related questions. If you have questions about how to setup your workspace use JabRef's Gitter chat. Try to open a (draft) pull-request early on, so that people can see you are working on the issue and so that they can see the direction the pull request is heading towards. This way, you will likely receive valuable feedback.

@aaronphilip19 are you still on it or can I unassign you?
