Adding environment variable DB_NAME to run.sh so that Gophish Container can be set up with mysql/mariadb.
db_name has to be changed in config to mysql for mysql connection to work.
Enables the user to add addresses that they expect incoming connections
to come from. Helpful in cases where TLS termination is handled by a
load balancer upstream, rather than the application itself.
The Dockerfile has also been rebuilt to use an unprivileged user instead
of root.
The run script adds more options and changes the method the
configuration is overwritten, which may help in situations where the
configuration is not owned by the unprivileged user.
