Update document to refer to the jira.field.resolution.include property

As of Jira 4.0 (JRA-16443), the jira.field.resolution.include property is available as a workflow property. This document should be updated to indicate this.

For instance, the header "Find out the IDs of the resolutions to be excluded." needs to be updated to indicate that resolutions can be either excluded or included. Maybe just update to "Find out the IDs of the resolutions."

Other paragraphs like "Exclude the resolutions in the workflow" do need update too...
