* New Switch Platform: TPLink Switch (HS100 / HS110)

### Information

The TPLink switch platform allows you to control the state of your TPLink Wi-Fi Smart Plugs.

Supported devices (tested):
HS100 (UK)

It should also work with the HS110.

To use your D-Link smart plugs in your installation, add the following to your configuration.yaml file:

"""
# Example configuration.yaml entry
switch:
  platform: tplink
  host: IP_ADRRESS
  name: TPLink Switch
"""

### Configuration variables:

host (Required): The IP address of your TPlink plug, eg. http://192.168.1.105
name (Optional): The name to use when displaying this switch.

* Update tplink.py
