Ia7 direct control for items with more than 2 states

[tobser]

Pull request also contains a small fix to raZberry.pm and ia7.

The main change this introduced here is a new ia7_config.json setting "direct_control_states" to specify the states for a direct controlled item:

    "Item_with_too_Many_States" : {
        "direct_control_states": [
            "on",
            "off"
        ],
        "direct_control": "yes"
    },

Ah, so the direct_control_states are the toggle, but that allows for other states to be present such as dim levels?

How does this show up in the IA7 user editable config file?

The item can have other states too. On click the new state will be set to the first state in direct_control_states. E.g. if the item has the following configuration:

   "test_item" : {                                                                                                                         
        "direct_control_states": [                                                                                                          
             "off",                                                                                                                          
            "on"                                                                                                                            
         ],                                                                                                                                  
         "direct_control": "yes"                                                                                                             
    },

and its current state is "20%" it will be changed to "off" when clicked.

Neat. We'll have to update the wiki with the new 5.1 ia7_config.json file.
