Subject: Add HAS_EXIF define

This brings a new HAS_EXIF define which is present when
EXIF information are available. Templates have been modified
to inform user when not available.

The test for EXIF metadata presence is fairly basic, we only look
for aperture, focal length and exposure time attributes. This might
be a subject to change in the future.
