Dropdown does not consider retained mqtt value

[alarik84]

Is your feature request related to a problem? Please describe.
Dropdown control is driven by mqtt message - basis on the message, it's switched to required value using val attribute. This works well but after device restart, despite of mqtt message witch is set with 'retain' flag it's set back to default val=0.

Describe the solution you'd like
After device is reset, it pull retined value for dropdown control and option is set accordingly. The same works well for slider control.

You will need to check the serial log while rebooting the device to see what is actually happening. openHASP doesn't really care about the retain flag or not, it just processes the messages as they come in. I suspect this is a timing issue or something else that overrides or resets the value after the retained messages is received... not sure what would cause this, but you should be able to trace that in the log.
