User Guide Chapter 9 - Social Networking

The two significant changes included:
* Updated Maps portlet.instructions based on new v3 API key
* Updated OpenSocial Twitter Portlet. The code needed to be updated based on Twitter Developer API changes. I now have a repository where this can be updated if changes are needed in the future. https://code.google.com/p/cdhoag-liferay/source/browse/Twitter.xml
