new feature Ignore error option for all nodes

[samwoo]

Hello,

I would like to request for the ability to have "Ignore Error" as an option against all nodes, and "Log Error" also as an option.  This will be useful where we may expect a record to not exist, we can ignore the check and progress to the next node.

In the event that future nodes requires information from this node, there should be a check in place that flags up a warning (the yellow triangles) warning the user of this.

Thanks,

Samuel
