* 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 Styling
