Limit max batch of images

There's an issue reported on slow devices when sending a batch of
images.

All the requests are send concurrently, and the sending of messages is
processed concurrently in the background.
On slow devices or connection with slow upload speed this may result in
expired envelopes, as the POW calculation or the upload takes too long,
and either they never leave the device, or worse they reach the
mailserver but won't be stored because already expired on arrival.

This commit allows setting the max-images-batch config value, setting it
to 1 for release and keeping it to 5 for other builds.
