v1.4.1

This release fixes #33 for CTS400

For Optima270/314 the T8 frost protection has been added. It needs to be manually enabled if you have it.

This release also removes the extract/supply air level sliders. These are unfortunately locked down at the device level and have only been confusing, thus being removed.

Also a decision has been made to internally rename the fan level selector from "select.fan_speed_select" to "select.fan_speed". This will result a new fan level selector showing up and the old one needing to be removed. I know this might be annoying, but i wanted to keep the naming more consistent.
