Update AndroidManifest.xml

Remove SDK from Manifest.  These values are not used, as the gradle build overrides them.   These values might be aggravating a Android Studio manifest merge bug when including the repo in a project with a different targetSDK.
Upgraded to Gradle 1.11 and Android Gradle plugin 0.9.+
Configured Github wiki as a submodule in docs folder
Updated release notes
