7. Apr. 2004 - Version 0.5
* added different startup-methods
* compatible with ATmega8 now
* included makefile adopted to ATmega8 now
(ATmega16 options still available)
* fixed jump to application which did not work
reliably before
* tested with ATmega8
* minimal options and startup-code result in
bootloader-size < 512 words
