There are no mpmissions in the server container when it starts for the first time. Ensure Chernarus is copied over as a default when this is detected, as the server is expected to start successfully. Presumes a default config where the map hasn't been changed.

Make development work by setting an environment variable.
Set the web container to restart instead of not, should the express server crash.
Copy XML files that are merged when the server  starts only when the mpmissions directory exists.
Refactor XML functions for better naming.
Handle display of lists when no mods are installed.
Add support for adding mpmissions for Deer Isle and mpmissions in general via mod integrations.
Add support for Red Falcon Watercraft XML files. WIP.
Add a deer isle DayZ bicycle spawn file.
