The new jmh plugin fixes a warning for the newer version of Gradle.
The new AppEngine plugin still produces a warning, but updating it
anyway so people know that upgrading the plugin doesn't fix the problem.
The new android-maven plugin fixes a build problem with the newer
Gradle.
The Visual Studio fixes were necessary starting ~4.4.

describes the change in behavior.
There's nothing immediately being used as part of this update. It's just
to keep us current and to get us over that Visual Studio change hump.
Updates include:
* Build file and dependency updates
* Correcting the gradle wrapper for the clientcache example
* Lint fixes (including making AsyncTask subclasses static)
* Dropping the m-prefix from member variables
* Fixing the code indentation
* Fixing and enabling proguard for the routeguide example.
