* Update cover.py
Blinds, Rollingshutters and Awnings did not set their respective device_class attribute
Previously they would all appear as device_class "window"
* fallback device class is always 'window'
fallback device class is always 'window' in the event we have an unknown cover type
* trailing whitespace removed, trimmed as well
* Update cover.py
## Description:
* Bump version to latest version of pyvlx: 0.2.10. Library more failure tolerant, when detecting an unsupported device.
* When calling API (e.g. run scene, change position) don't wait until device has reached target position (This caused HASS to be flaky while the device was moving)
* Support for vertical and horizontal awnings.
