Ticket: https://issues.openmrs.org/browse/GCI-38
Melange task: http://www.google-melange.com/gci/task/view/google/gci2014/5040692569047040

For this task, I merged the widgets I made for [GCI-41](https://github.com/openmrs/openmrs-contrib-id/pull/43) and [GCI-42](https://github.com/openmrs/openmrs-contrib-id/pull/49) (hence the numerous commits).
