1.0.6 - support v1.6.6 of IDE, improved support for weird clock frequencies

• Fixed issues in 1.6.6 of the IDE (such as including avr libraries failing to compile and spurious library warnings)
• Added support for enabling compiler warnings. (note - with warnings enabled, you will see pointer-to-int and int-to-pointer warnings. These can be safely disregarded)
• Added support for WAY more clock frequencies, including optiboot builds and optiboot serial1 builds.
• Fixed micros() and delay() at weird frequencies. (note - micros() takes a bit longer to return on weird frequencies)
• Fixed micros() and delay() at < 1 mhz
• Fixed support for ATtiny441
