Scaling issue when loaded in landscape, locks to portrait.

I was manually forcing portrait in AndroidManifest, which led to random scaling problems 20% of the time on load.

Turns out this plugin creates same exact issue, so I'm assuming it's something beyond it's control within the android cordova viewport initialization or something?

For details: https://github.com/apache/cordova-android/issues/1500

Start with the plugin's Android orientation initialization and the AndroidManifest setting described in the report, then compare the behavior with cordova-android issue 1500. Reproduce the landscape-load case and determine whether the plugin or Cordova viewport initialization is responsible; done means orientation changes no longer cause intermittent scaling problems.
