bin/app-env - add this environment creating wrapper script

designed to be run a bit like env,

   app-env hypnotoad something

it modifies PATH, PERL5LIB etc. much like local::lib so that all the
dependencies can be pulled in.
lib/MossMap.pm - add a stub top-level module, for docs/packaging purposes
Cheshire-Dataset.csv - remove
dist.ini - add a dist-zilla config
dist.ini - stop using autoprereqs

It's not especially reliable.
dist.ini, .gitignore - adapt for carton
cpanfile.snapshot - add this carton config
dist.ini - turns out we need SQL::Translator
moss-map.example.json - fixup
moss-map.example.json - make heartbeat_timeout longer

uploads are very long running worker processes
moss-map.pl - allow configurable logging

hypnotoad otherwise gives no clues.
s/ll/local/g - local-libs now go in local/
moss-map.example.json - add passphrase config
public/upload.html - remove this, obsolete
public, t - reference physical files rather than symlinks

Since the symlinks aren't perpetuated by dzil's packaging, this means
we either do this or run a script on install to recreate them.

Also, remove the symlinks.
