Allow multiple photos with reports

A new CONFIG.MAX_PHOTOS setting enables any number of photos to be
uploaded.

Includes code adapted from from 0ac07c1ea062a68d68d162c3ecdbba7e9da3e4c9
and c207193a0e052ae9e41a6d42e0ac1b704883b25b in zurich_mobile: this is a
bit of an abuse of the FileTransfer plugin, which technically doesn't
support uploading more than one file at a time. There's no good reason
for that though, the HTTP spec allows an arbitrary number of files in a
POST request.
