Added tests for static pages

Also added in drag and drop helper.  Please be careful using this method as it is truly a hack to obtain the visual effects.  As of this commit, selenium does not support drag and drop for jQuery sortable items

+Feature: Static Pages
+    As a course author, I want to be able to add static pages
+
+    Scenario: Users can add static pages
+        Given I have opened a new course in Studio
+        And I go to the static pages page
+        When I add a new page
+        Then I should see a "Empty" static page
+
+    Scenario: Users can delete static pages
+        Given I have opened a new course in Studio
+        And I go to the static pages page
+        And I add a new page
+        When I will confirm all alerts
+        And I "delete" the "Empty" page
+        Then I should not see a "Empty" static page
+
+    Scenario: Users can edit static pages
+        Given I have opened a new course in Studio
+        And I go to the static pages page
+        And I add a new page
+        When I "edit" the "Empty" page
+        And I change the name to "New"
+        Then I should see a "New" static page
+
+    Scenario: Users can reorder static pages
+        Given I have opened a new course in Studio
+        And I go to the static pages page
+        And I add a new page
+        And I "edit" the "Empty" page
+        And I change the name to "New"
+        And I add a new page
+        When I move "New" after "Empty"
+        Then I see the order is "Empty New"
