11 *** EMERGENCY BUGFIX ***
- Signal rd_o was corrupted in last version. wr_o and wr_n are not effected.
- OP JMP (indirect) produced a 65C02 like jump. On 6502 a special case exist
when the (indirect) address cross the page boundary (e.g. JMP (02FF) reads
from $02FF and $0200, instead of $02FF and $0300)

5 Bugfixes for all relationchips with interrupts BRK, IRQ and NMI.
The control for the stack pointer within fsm*s of BRK, IRQ and NMI was incorrect. The stack was allways growing up instead of growing down.
The "B" status flag was never set within BRK.
The relationchip between addresses and data while writing onto the stack was badly misalligned.
