Modified Adafruit_Trellis.* to handle __AVR_ATtiny84__ define, and moved
'Wire -> TinyWireM' redefine into the header. Also updated the examples to
remove the explicit '#include ' which clash with the redefine.
Tested: TrellisTest compiles and runs on ATTiny84, TrellisLightsOut and
TrellisGameofLife compile with 'low memory' warning.
