Display translators with authors

[juliajbeine]

As discussed in this issue, translators may be encoded in the <titleStmt> with <editor role="translator">. However, in the frontend, only authors are displayed. For instance, see the translations of Euripides' and Sophocles' plays in NeoLatDraCor. From my point of view, it would be good to also display the translators, especially in corpora that are not only dedicated to translations.
If the encoding <editor role="translator"> was our recommendation, e.g. in the ODD, we might display translators together with authors automatically and uniformly.
@lehkost, @cmil, @markschwindt, what do you think?

@lehkost, @markschwindt, do you have any preference for the frontend regarding this issue yet?

As discussed during the jour fixe, I introduced <editor role="translator"> in GerShDraCor (commit). The next step would be to display this info differently in the frontend.

We can also discuss where else we want the info on translators to appear, e.g. in the metadata files. The info that a play has a translator might also be used to distinguish original plays from translated plays.
