Add support for download of world in zipfile

Browse Source 
WORLD=http://hostname/world.zip
Zipfile should contain world/ directory, and optionally any required mods in mods/ as well as optionally
a default server.properties file (overwritten by any env vars)
Also export volumes /mods and /config, the contents of which are copied to /data/mods and /data/config.  This
allows shared read-only mounts for modules without affecting world.
