Reworked object command tables.

Browse source 
Object commands used to require re-adding every call in the script parent's __init__ or factory functions, adding the commands to a new command table directly on the object. Since all other attributes can be set up in at_object_creation(), this was both inconsistent and a bit confusing to work with. There is now a method add_commands() directly defined on all objects. It takes the same arguments as the normal add_command()o but use a reserved attribute to create and update a command table on the object. This has the advantange of completely removing the __init__ call in the script parent, all definitions can now be kept in at_object_creation() and are, more importantly, persistent without having to be recreated every call.
- I updated the examine command to show all the commands defined on an object (if any).
- I updated gamesrc/parents/examples/red_button.py considerably using the new command methodology and also using the updated Events.
