New platform support: Digital Loggers relay (#1528)

Docs from prior work when I didn’t know what I was doing with git, branches or open source contributions.  There are still changes to be made on the code side and this will doubtless be updated.

+
+The `digitalloggers` switch platform allows you to control the state of your [Digital Loggers](http://www.digital-loggers.com/dinfaqs.html) switches. 
+
+To use your digitalloggers switch in your installation, add the following to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+switch:
+  - platform: digitalloggers
+    host: 192.168.1.43
+    password: SuperSecret123!!
+    name: FantasticRelayDevice
+
+```
+
+Configuration variables:
+
+- **host** (*Required*): The IP address or FQDN of your DIN III relay, eg. `192.168.1.32` or `myrelay.example.com`.
+- **name** (*Optional*): The name to use when controlling this relay.  Default: `DINRelay`.
+- **username** (*Optional*): Credentials for controlling this relay. Default: `admin`.
+- **password** (*Optional*): Credentials for controlling this relay. Default: `admin`.
+- **timeout** (*Optional*): Default timeout as set by the underlying python-dlipower library is `20` seconds.  Override it if you need to.  Valid range is 1 to 600.
+- **cycletime** (*Optional*): This is the delay enforced by the library when you send multiple commands to the same device.  The default relay cycle time is `2` seconds. Override it if you need to.  Valid range is 1 to 600. A delay is a recommendation of Digital Loggers: 
+>Many loads draw more power when they are initially switched on. Sequencing prevents circuit overloads when loads devices are attached to a single circuit. 
+
+
+Your relays will be available in the form `switch.fantasticrelaydevice_individualrelayname`
+
+**Note:** There is currently a limitation of the [dlipower library](https://github.com/dwighthubbard/python-dlipower) used by the `digitalloggers` component that communication is only available over port 80.
