Moved kxml2-2.3.0 library from libs to a new folder plib.  The libraries in the "libs" folder are automatically included in the android private libraries which are alos automatically exported. This causes a problem when the android application is included as a library in another application. In this case fieldTask.  There is a conflict between the XmlPullParser in kxml2 and the same class in android core.  This change means the the kxml2 library will not be exported which avoids the clash.
