Changes to make the sample apps import into Eclipse easier

- Changed the target from 7 and others to 17, which is the latest api
level, and the recommended practice.

- changed classpath javadoc location to be relative to the docs folder.

- Added chutesdk to the ReviewSubmissionExample app. It was throwing
errors for those classes.
