Initiative filter for "in Progress" should filter out "not started" items as well as "achieved" items

The "in progress" filter on the initiatives pages filters out "abandoned" and "achieved" initiatives but it leaves "not started" inititiatives on screen.

Add more flexible filtering using a drop-down list instead of the All|In progress links used today. The filter options should include:

• All
• In progress
• Completed
• -------------
• < List of all relevant workflow statuses>

The same filter options should exist at the top of the Timeframes dropdown. 

And the Releases and Features lists. For the releases and features filters the dropdown needs to include workflow statuses from all products that have linked releases or features.
