Closed tickets are scheduled to future with resource leveling

[anonymous]

When "resource leveling" is on, closed tickets are getting "planned" to future even though they are:

• closed
• have start date and end date set explicitly
• have "worked hours" set to "estimated number of hours"

I have a partial fix which queries "actual" start (first transition from new) and finish (last transition into closed) from the ticket database. It needs refinement before I can push it but I think it will address this issue.

[Chris Nelson]

(In [12750]) Get actual start and finish for active and closed tickets. Refs #9648, #10717.

Use these dates in scheduling.

Note that closed tickets don't require resource leveling, display their actual start and finish times.

This defaults to disabled (0) and can be controlled by useActuals option in the TracPM section of trac.ini (1=use actual dates, 0=schedule). The useActuals parameter to the Gantt chart macro overrides the TracPM value.
