Other small bugfixes, fixes to @dig to properly call creation hooks of all newly created objects (it was not setting anything before). Also fixed some of the annoying bugs around using several of the building commands that didn't properly handle spaces around the separator = symbol.

GLOBAL_STATE_TABLE.add_state() before adding commands to it. The state can now be much more configured by including as much or as
little of the normal default commands into it as wanted (so you can now have states which are almost as normal, except some
commands are missing or change their behaviour ... illness or darkness comes to mind). The possibilities here are limitless.
* States now also optionally allow traversing exits as well as using command tables defined on objects.
* States now better handle error messages (so if you try 'look' in a state which does not contain a look command you will no
longer get the 'Huh?' but will be told that the command is not available at the moment).
* All examples in commands/examples/ have been updated to use the new State system. Also added a @test_state function for trying out
the functionality.
* Added hooks at_before_move() and at_after_move(), useful for character based move-restrictions and checks (e.g. movement speed)
* Minor tweaks to the event system; avoiding the counters to go negative should they hit an uncaught traceback.
* Small fixes of typos and minor extra safety checks.
