Comment 3 for bug 1277186

In qml/Keyboard.qml the swipeArea.drag.filterChildren=true flag was causing drag events in the area between the top keys and the border to be ignorned. Need to set that to false by default and only set it to true if the wordribbon is visible so you can swipe down from the wordribbon as well. WordRibbon is actually a child of the swipeArea.
