[Android] Compatibility with Cordova 1.5.

The following LOC does not work with Cordova 1.5.0.
Intent i = this.ctx.getIntent();

Changed it to:
Intent i = ((DroidGap) this.ctx).getIntent();
Added an import org.apache.cordova.DroiGap;

The resultant code works with Cordova 1.5.

Also, commented the unused import: import android.util.Log;
