Rebased the bugfix from the original Google Code issue #292 to work with Arduino 1.6.x
Description of original fix provided by Pete62:
The later 8 bit AVR's use two registers (TCCRxA, TCCRxB) whereas the ATmega8 only uses a single register (TCCR2) to house the control bits for Timer 2. Bits were inadvertently being cleared.
Made some helper class for files filtering.
platforms.txt now contains only one platform at a time.
Some cleanup in Compiler and AvrDudeUploader classes.
