Listing: Language setting for "Edit Media"

[Jnnis]

In the "Language" tab we have the possibility to change a lot of strings individually for a listing typ. For example: "Edit Listing" and "Add Media". 

So we are able to speak of "pictures" instead of media for a listing typ. To make this feature even better, it would be good to have also the ability to change "Edit Media" wording. So it can be named fitting to changes made in "Add Media". For example: "Edit picture(s)" instead of "Add picture" and "Edit media".
