Changed FeatureActionResult to FeatureActions

As a result of our discussions in meetings today, we decided to:

1.  Remove ResultID from FeatureActionResult
2.  Rename FeatureActionResult to FeatureActions
3.  Create a new FeatureActionID as the primary key of FeatureActions
4.  Link FeatureActions to Results via FeatureActionID
Merge pull request #37 from UCHIC/Modified_FeatureActionResult
