The system of dynamic ID

[Disinterpreter]

Is your feature request related to a problem? Please describe.

When you have many players and play in the game, using the GUI can be inconvenient. So, I suggest implementing an ID system for flexible interaction with different things.

When will it be useful?

1. For notifications, like when you put in chat Hi %5! you've got Hi patrik!
2. Commands with communicating with players like /pm 5 Hi! sends the message to the player with ID 5.

Describe the solution you'd like
A temporary ID system is comfortable for communicating and executing commands from char or console.
How it will work:

1. When the resource start we make space for accounting players by ID
2. When the player joins we check the last ID and add it to the player plus 1.
3. When the player leaves - we delete his ID from the space.

Moreover, it will contain an export function for getting players by ID.

element/player getPlayerByID(int id)
