* Remove sleeps.
- the sleeps is not needed.
* Make sleep depending on environment variable.
- set QUICKWIZARD to true to disable sleeps.
* Changed env-name and made it work without env.
- It only worked when environment variable was defined. Now it works
with variable unset, which should be the normal case.
- Added ESPHOMEYAML_ as prefix so it's ESPHOMEYAML_QUICKWIZARD.
