Google Code-in

We are migrating to a new activity server (ASLO3) and in the process are trying to do some housekeeping. We have a spreadsheet with a list of acitivites that are missing their license field. The task here is to figure out the proper license and to add a LICENSE file to the repo via a github pull request. (Note that some repos use COPYING instead of LICENSE, which is OK.) The license is usually evident in the .py files. (Also, please ensure that there are both a repository field and a license field in the activity.info file and that the repository field accurately points to the correct repo.) Do ten activities to complete the task.
