1.1.10 - Wire, EEPROM fixes, ADC enhancements!

The library changes in 1.1.9 brought a few bugs, largely because I implemented them without testing them (because wiring.c was in pieces at the time....) and forgot I hadn't compile-tested them when I released 1.1.9. Those two libraries work again. Also, I made some fixes to the ADC - you can now use it to read the internal reference and temp sensor, making measurements of operating voltage and temp easy. See the included example - we now have a dummy library called "megaTinyCore" with examples of part-specific features!

This is the version for board manager installation
