Fixed the Carry to work properly.
Checking if the ninth Bit is one or zero.
Merge branch 'hotfix/carry'
Added a resetting routine of the DigitCarry if there was no DigitCarry.
Changed the DigitCarry calculation. Now the 4th low order bits are added and in the result is checked if the 5. bit is set or not.
Also changed the calculation from SubLW and SubWF. They are now using the two's complement and adding instead off subtraction.
Merge branch 'hotfix/digitCarry'
