Allow console to create a game

[mdsimmo]

What problem does the feature solve
The console is not able to create new games since the /bm create command is required to be run by a player to get a position. It could be useful for the console to create new games to automatically generate a queue of games.

Describe the solution you'd like
Add a -p argument that lets the console specify the position. Then dynamic creation of games will be possible.

Describe alternatives you've considered

• Add a -t target selector that the console can target a player/entity. This would only mean that in most cases an entity will need to be spawned so it's position can be selected. It may seem to have the advantage that multiple games can be built at once, but ultimately I cannot see how multiple games could be built at once due to what would the games' name must be unique?
• Add a command similar to Minecraft's /exec, which allows the position to be set.

Additional context

• One issue with this solution is that it is not possible to use dynamic position, which makes the feature largely useless (unless combined with another plugin that allows dynamic command creation).
• The game name is also not dynamic, thus, again the feature is largely useless on its own without some sort of dynamic command builder.
