Samples, cordovaCamera

Suggestions
1

E.g. cordovaCamera sample update could be useful.
Line with specification of engine is missing in config.xml. Spec is very old. Whitelist line still existent:

<plugin name="cordova-plugin-camera" source="npm" spec="2.4.1" />
<plugin name="cordova-plugin-whitelist" source="npm" />

Good suggestion. It will be in the next build.
