support for exit code (different from invert logic)

[YAMLcase]

exit codes from the exec node should be treated as:

• 0 is true
• any other number is false

inverting the logic as with #1 is a decent workaround, but not sufficient because other inputs, true, false get inverted.

Probably the best way is to add a new input handler for payload.code: int, but I'm not sure how difficult this would be compared to the node providing a new option for "invert int only" and having the user change input field to msg.payload.code.

Below is an export of my test bed using the linux commands true and false:

Hi, thanks for the contribution.

Maybe I'll add some docs in future to make this feature more transparen/present.

[SimonButtazzi]

Feature is included in v1.4.5
