partially completed tasks should be remainghours long

[maikb]

Using the TimingAndEstimationPlugin, the length of each task seems always to be fixed to estimatedhours. This causes the following miss behaviour:

• Using ASAP scheduling, succeding tasks of an incompleted task start to late.
  
• Using ALAP scheduling, incompleted tasks start in the past even if the are on-time.
  
• In any case, the plan does not include any delay (remaininghours > estimatedhours).

To calculate the percentage of completion, totalhours/estimatedhours still could be used. Thus, completion = 100% and remainghours > 0 indicates that a task is to late. But you still would see the actual estimated remaining effort (remainghours = delay).
