simple creation of maven artifacts, directory reorganization, and colors.xml

moved AndroidManifest.xml, /res, and /src/main/java/* into base dir. modified build.grade to include new source sets and changed the uploadArchives task to push maven artifact to /build/mvn-repo. added instructions for use as maven dependency, use as module dependency, building, copyright, and license to README.md. fragment_submit_log.xml now uses '@color/submit_confirmation_background' instead of hardcoded '#44ff2d00'.
