Console Unify API Changes (#3059)

* Remove unused IChatCommand.

* Lots of refactoring into a shared context.

* Removed ICommonSession from server concmd Execute.

* Added argStr parameter to concmd execute.

* The execute function of client concmds now returns void, use the new shell.RemoteExecuteCommand function to forward commands.

* Finally move shells and commands into shared.

* Console commands can now be registered directly without a class in a shared context.

* Engine API Changes.

* Repair rebase damage.

* Update Submodule.
