Add a functionality that promotes player to admin role

It could be nice to add a feature that download and automatically install server for nubs

Sometimes all the data of the world is reseted when we restart the containers

test closing issue

Right now, some of the targets are not working anymore

Available this functionnality

When deleting the data directory, ask the user if he's sure to want to loose its data (e.g. minecraft worlds)

When I run the command curl -s -L https://raw.githubusercontent.com/SaphireVert/docker-minecraft/master/install.sh | bash -s, there is this error : read: -p: no coprocess

It could be nice to add possibility to set other server properties (like ops or spigot.conf).

When cloning the repo one get more than 31Mb because of some files in the git history:

It would be nice for everyone to remove them. See https://stackoverflow.com/a/42544963 to reproduce this output.

Specify install steps

Newbies have not way to accept the EULA when using install.sh, resulting in:

spigotmc_1    | [19:17:22] [main/WARN]: Failed to load eula.txt
spigotmc_1    | [19:17:22] [main/INFO]: You need to agree to the EULA in order to run the server. Go to eula.txt for more info.
docker-minecraft_spigotmc_1 exited with code 0

E.g., use a second docker-compose file (docker-compose-slave.yml) to be able to launch a Minecraft server only with spigot, without using bungeecord. That would also implies that the ENV vars are set accordingly.

docker-compose -f docker-compose-slave.yml up

Now, some functions doesnt' work anymore because of repos's name (f. e. git clone)

Masterserver: online mode to false in server.properties and bungeecord to true in spigot.yml.

All is in the title

When someone just clone and "make up" this repo, the setup fail to provide a workind environment.

Now that the project include a docker-compose.yml file, the Makefile shoud use it.

Add comments line before each target in the Makefile

A list of minimum steps with some explanation won't hurt...
