Fixes for a couple of bugs.

Idle Sleep Delay - If your device is a bit too aggressive about going to sleep while you are trying to use this tool, this option is for you. A new toggle switch can be found under the MQTTool App Settings. If you enable this switch, the device will wait 5 minutes before automatically going to sleep. Note: This sleep delay will only be in effect while the MQTTool app is open, connected to a broker and subscribed to a topic. Otherwise the device's default sleep timer applies.
