Multiple messages in the SnackBar

[EduRibeiro00]

Previously, the SnackBar component could only display one message at a time, and messages that were created quickly were displayed in sequence and became obsolete because there was a more recent message waiting to be displayed.
The changes made allow for the SnackBar to display multiple messages in the same component, each in a different line.

Changes that are still to be made in this PR:

• Increase/Reset SnackBar timeout when a new message is added
• Add a maximum limit for the number of messages displayed at the same time in the SnackBar
• Gradually remove old messages from the SnackBar as they timeout

Fixes #7340.

• Change in CHANGELOG.md described in a way that is understandable for the average user (if applicable)
• Tests created for changes (if applicable)
• Manually tested changed features in running JabRef (always required)
• Screenshots added in PR description (for UI changes)
• Checked documentation: Is the information available and up to date? If not created an issue at https://github.com/JabRef/user-documentation/issues or, even better, submitted a pull request to the documentation repository.

I'm having difficulties in finding a way to increase or reset the toast display timeout, so the new messages added to the SnackBar can be displayed the right amount of time. There seems to be no way of modifying the timeout of an already displaying event... I've tried closing the SnackBar and firing another event with the new messages, but that leads to weird closing and opening animations.

A quick and dirty way would be to resubmit the previous event before submitting the combined event. According to
https://github.com/sshahine/JFoenix/blob/2dbb8515da236140c41eabe22eb549b458f1e867/jfoenix/src/main/java/com/jfoenix/controls/JFXSnackbar.java#L312-L317
this should reset the timer. Another approach would be to use reflection to get the pauseTransition and call playFromStart on it.

@EduRibeiro00 I found this PR while cleaning up the mass of opened tabs in my Firefox. May I ask whether you could find some time these days? We are having JabCon and could provide fast feedback.

Hello. Unfortunately I cannot make this a priority in the next coming months, so I suggest moving this issue to another person. Sorry :/
