[COMMANDS] - Extra QoL commands

[Lithrun]

How will this feature improve the game?
Over the years of hosting expeditions, I've created a generic custom logic file which contains a lot of convenient command useful for hosting. It contains a large set of useful commands, and these can be integrated directly within the game. Some examples:
/revmc - Revives all players at the location of the MC
/revset - Revived players will spawn at the location of the MC when this command was used

It also features useful commands for spawning titans in a random locations. Refer to: https://github.com/Lithrun/aottg-generic-logic

Describe the functionality of the feature
Convenient commands from the generic logic are to be added as part of the default commands available to the player. Together with other commands suggested by the community.

Don't start on this issue until we have compiled a list of commands + functionality
