1. Requesting jump is possible with command /dummy jump <id> or from code:

Dummyuser.Jump();

2. Requesting enter/exit is also possible with command /dummy ride <id> [--exit].
3. Will look into later.

I'm planning to rewrite this project to make it modular for my future projects, but no time at all

• Fix problem that causess not giving /admin to dummy

Do /unadmin on the dummy then do /admin, that seems to work
