#247 Primavera import changes + test cases

[Nathaniel Marrin]

Changes made to the library to align pmxml import with the xer import. I have attached a patch, changed files as well as sample data in both xer and xml formats for review.

MPXJ Changes

PrimaveraPMFileReader.java

- Added Project ID to match value from PrimaveraReader
- Change setPercentageComplete to support Physical Percent, Duration Percent and Units Percent. The percent complete method is captured in the PercentCompleteType field.
- Changed baseline values to match values from PrimaveraReader. target_ values match Planned
- Added ActualDuration to match value from PrimaveraReader act_drtn_hr_cnt
- Added Duration. This is the completed duration or the current task duration taking into account actual and remaining (Actual + Remaining is captured in AtCompletion values)
- Changed LateStart, LateFinish, EarlyStart, EalryFinish values to pull from correct XML fields
- Start and End should come from the start and end date xml values. This covers the case where the task is running late and hasn't been complete. Remaining Start / End date
- Added MILESTONE_MAP and milestone logic from PrimaveraReader 
- Mark a task as critical when the late start is less than or equal to the early start. This takes into account Primavera negative float
- Add cost data to tasks when the resources are processed. This is so that we include material values in the actual, remaining and baseline cost values

PrimaveraReader.java / PrimaveraXERFileReader.java

- Start and End dates should look at restart_date and reend_date for open tasks. This shows the correct dates when a task is running late

Thanks for updating Git.

Looks like the merge brought in comments for setLateStart, setEarlyStart, etc. Attaching a patch from git.
