Copy the filename inside Draft/Upload-dialog #56
Description
This could perhaps be a clipboard-button next to the filename section, or alternatively just tapping the filename to copy to clipboard.
This is useful to re-use the filename in UIs outside the app (eg. OSM).
Alternatively, after upload, the filename (and other relevant text fields) should also be copyable in the detail view of the uploaded file.
This feature could be incorporated with a general improvement of the filename-editing (eg. tap/longpress to edit as custom, instead of going through the menu).
