Changed 'x' specification (ignore) to 'i' (input) allowing the developer to preserve or change the bit as desired.

According to the datasheet the least significant bit of the extended fuse byte of an ATMega169 is reserved and should not be programmed. In the corresponding write command in avrdude.conf this bit is marked as "ignore" ("x"). This causes the bit to be set to zero and thus the reserved fuse to be programmed. Atmel confirmed that the programming of this bit affects the RESET pin so that further SPI programming is not possible. I had to switch to JTAG to reset this fuse bit.
I think the avrdude.conf needs to be corrected.
