Update the RFLink Docs to read better (home-assistant#3758)

philhawthorne · fabaff · commit 5e20b56f8355 · 2017-10-26T08:47:13.000+02:00
Makes some slight adjustments to the RFLink component documentation to
remove some grammer and spelling mistakes.

Alos changes the domain which the docs point to, as the domain name
mentioned has been moved.

 Even though a lot of devices are supported by RFLink, not all have been tested/implemented. If you have a device supported by RFLink but not by this component please consider testing and adding support yourself or [create an issue](https://github.com/home-assistant/home-assistant/issues/new) and mention `@aequitas` in the description.
