Homematic Support

[danielperna84]

Description:
Adding bi-directional Homematic support. This includes lots of actors (switches, rollershutters etc.), thermostats and sensors (motion, brightness, shutter contacts etc.). I roughly estimate that we cover more than 60% (maybe even more) of all the currently available Homematic RF products, which are widely spread in Europe (primarily Germany, Austria and Switzerland).
Configuration of devices might be complex, but we'll cover that in the documentation (working on that). Basic setup is described within the component/platform files.
We also have an (experimental) autodetect feature, which discovers and configures every device we're capable of handling, although without friendly names. But for beginners this will quickly show which of their devices are supported and can be manually configured accordingly.

Thanks to @jazzaj for starting the Homematic implementation based on my pyhomematic module.
Thanks to @pvizeli for making radical improvements to my module and jazzajs implementation.
Thanks to @bimbar for support of MAX! Thermostats.

If user exposed functionality or configuration variables are added/changed:

• Documentation added/updated in home-assistant.io

If code communicates with devices:

• Local tests with tox run successfully. Your PR cannot be merged unless tests pass
• New dependencies have been added to the REQUIREMENTS variable (example).
• New dependencies are only imported inside functions that use them (example).
• New dependencies have been added to requirements_all.txt by running script/gen_requirements_all.py.
