	* BaseTinyFirmware/IAR: Port Martin's changes from 2008-04-03
	to IAR

	* BaseMegaFirmware/GCC: Experimental Master Code for the ATmega644
	with basic "drivers" for
		- keys incl. power-off with debounceing
		- 74HC595 low-level "software-SPI"
		- LEDs though 74HC595
		- Power-off and Slave-Reset control though 74HC595
		- hardware SPI for comm. with slave
		- simple test-function for communication with slave
	* BaseTinyFirmware/GCC/statefunc.c:
		- prevent unneeded writes to eeprom if init fails
		- prevent slave from entering sleep-mode standby if
		"MASTER_INT" is low (so SPI communication with master is
		possible even during the "8-second watchdog delay")
