Re-implement "Customize entry types" dialog

[tobiasdiez]

In #4716, the Customize entry types dialog was temporarily removed. It should be rei-mplemented in JavaFX once we converged to a stable entry editor layout (refs #2790 #366 #4687 #4688).

Can I customize them manual?

[tobiasdiez]

@burrbull you can use an older JabRef version (e.g. 3.4.1) to customize the entry types and then use the customized types in the new 5.0 version (only the customization dialog was temporarily removed, not the functionality). Sorry for the inconvenience.

The dialog shows like that:

When working on that, #725 should also be addressed

Is there a way to do this by manually editing some configuration file (instead of trying to mix JabRef versions)?
For some reason I do not have an Editor field available for @book entries and I would like to add that somehow.

Sure, custom fields and custom entry types are all stored in the metadata at the end of the bib file.
You can always manually add the field also in the source-editor in the tab of the entry editor, e.g. editor= { The book editor}

Edit// I am currently reworking the dialog. Should hopefully be finished soon. See #5799

Thanks, I am happy to manually add something to the bib ... what would the metadata at the end of the bib file have to look like in order to simply add the editor field to @book entries?
