Add Player.enterVehicle

[Advers]

Adds a function to allow forcing players into seats. This could be abusable, so it's restricted to "admin only" permissions by default, and also requires entity permissions on the player and the vehicle.

I don't think we need a entity permission check on the vehicle. However, I'm wondering if the CanPlayerEnterVehicle hook should be checked.

Honestly, introducing an optional player argument to Entity.use that's only available to superadmins could work too and be more versatile.
Wouldn't have to deal with checking the hook (if that's needed) and could be used for other purposes as well.

Could also implement admin-only Player.use that would work the same as Entity.use, but the entire function would require admin perms and take the entity as an arg instead.

I think use() has the same problem in that it bypasses PlayerCanUse. Might be wrong tho

Also, I think its preferable that enterVehicle can bypass in-engine vehicle locks

However, I'm wondering if the CanPlayerEnterVehicle hook should be checked.

Player.EnterVehicle already obeys CanPlayerEnterVehicle by default. It would be redundant to add an extra check.
