LEAmDNS Fixes 1.1 (#5619)

Browse Source 
* Fixes 1.1

- Better separation of ESP wifi thread code from user thread code
- Added a flag for 'update()'-less use (disabled by default)
- The too fast updates for service queries are fixed
- Switched fully to PolledTimeout; LEATimeFlag not needed anymore (BTW: a const 'expired()' method would be helpful)
- The device should stay visible now even after the first TTL timeout
- Improved service querying (queries five times now)

* Update mDNS_Clock.ino

Removed references to LEATimeFlag.h

* Update mDNS_Clock.ino
