Move dagger-android tests to Gradle test sources

* Fix the Java resource folder for Android projects to be in 'resources' and not 'res' as the latter is for Android Resources (styles, images, layouts, etc).

* Add proguard files to dagger-android, these are added as part of the resources instead of being generated by the dagger-android-proguard-processor as this is easily supported in Gradle.
