User is not informed when Exif is not scrubbed

1. Send image, uncheck Send image with the original size
2. Download, learn that Element auto-strips sensitive EXIF metadata, love it
3. Read no mention of datetime, make and model, IDs on the checkbox, infer it is safe to tick (false sense of security)
4. Send image to Mr Evil, do check Send image with the original size
5. Sensitive EXIF metadata was sent.

For clarity, lack of communication that EXIF was stripped is safe, the worst case is an inconvenience. This issue is about lack of communication that EXIF was not going to be stripped.

I am not sure if I should open a separate issue for this because it is somewhat diferent but it is not nice that element strips exif data away. In #465 it was asked to automatically strip exif data away. I do not like that the gps location is lost when sending an image. It would be nice to have the option to preserve all exif data. When I send an image in original size, I actually expect that the original image is send and not that the exif data is removed. When I send a compressed image, I could assume that exif data is removed but even then, I actually assume that only the size is smaller. It is nice having the option to remove exif data to reduce the neccessity of apps like “scrambled exif”. It is not nice that I am not able to use element to send an image of a friend I just took to this friend because exif is removed.

#465 is about enabling EXIF stripping. Some ideas were described in that issue, such as an explicit option buried deep in the settings that few people will read; automatic choice based on the image source. These do not necessarily address the concern of communicating that EXIF is not going to be stripped. An explicit, prominent confirmation dialog or option displayed just before sending would address both issues IMO.
