android_ignore_translation_errors.js

// add additional build-extras.gradle file to instruct android's lint to ignore translation errors
// v0.2.0
// New version is a compatible Node module and only appends/write to file if it is 
// empty or does not exist.
// causing error in the build --release
// Issue: https://github.com/phonegap/phonegap-plugin-barcodescanner/issues/80
//
// Warning: This solution does not solve the problem only makes it possible to build --release
