Create "thin" build type and clean up previous commit.

The "thin" build type relies on system scala library, while "debug"
and "release" provide the library itself.

 Building
 ========
-To build, run `./gradlew assembleDebug` or `./gradlew assembleRelease`.
+To create a debug apk, run `./gradlew assembleDebug`. Alternatively, you can use
+`.gradlew thinDebug` for a faster compile, but this requires Scala libraries installed
+with [Android-Scala-Installer](https://github.com/Arneball/Android-Scala-Installer) on your device.
+
+To create a release apk, run `./gradlew assembleRelease`.
