TTP229-LSF i2c device support (#205)

* add ttp229-lsf docs

* fixed link to datasheet

* remove indent

* type image filename

* convert image to jpg

* Update ttp229.rst

- Change id in example to name. Reason: otherwise it won't show up in frontend and users will be confused
- Reorder conf options
- esphomelib -> esphome

* Remove disqus

+    ttp229_lsf:
+      id: ttp229_device
+
+    binary_sensor:
+      - platform: ttp229_lsf
+        name: TTP229 Channel 0
+        channel: 0
+
+Configuration variables:
+------------------------
+
+The configuration is made up of two parts: The central component, and individual Binary sensors per channel.
+
+Base Configuration:
+
+- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor.
+
+Binary Sensor Configuration:
+
+- **name** (**Required**, string): The name of the binary sensor.
+- **channel** (**Required**, integer): The channel number at the ttp229 the touchkey is connected to.
+- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
+- All other options from :ref:`Binary Sensor <config-binary_sensor>`.
