fixed a problem with m8515 UART.
...
UBRRH and UCSRC share the same io register location, bit URSEL needs to
be set in order to access UCSRC!!

flashing older nodes across t03 now works!
...
older nodes need the new bootloader which doesn't depend on pagesize because
those older nodes used quite large message sizes which are not supported
across t03 nodes (we would need to much RAM on t03 for this).
