[Feature Request] Export the conflicts report

[claudejdev]

The conflicts report is a useful feature for a modder and thus it would be great to be able to export the conflict report in a single text file.

[ThibautSF]

Note: It can be exported manually → Ctrl+A to select all and copy paste. (the temp solution)

TODO :

• Add "Export" button in dialog ListCreator.displayConflicts()
• Open a javafx FileChooser
• Write the file
