Add removeItem method to the API

[adam-s]

AsyncStorage.removeItem() doesn't exist for Android. Can the API include this and the other methods? I've been using AsyncStorage.set('key', null) as the work around.

getItem
setItem
removeItem
mergeItem
clear
getAllKeys
flushGetRequests
multiGet
multiSet
multiRemove
multiMerge

Adding the following to java/org/gamega/RNAsyncStorageModule.java will add removeItem

/**
  * Write string value by key
  * @param key
  */
 @ReactMethod
 public void removeItem(String key, Promise promise){
     try {
         SharedPreferences sharedPref = getCurrentActivity().getPreferences(Context.MODE_PRIVATE);
         SharedPreferences.Editor editor = sharedPref.edit();
         editor.remove(key);
         editor.commit();
         promise.resolve(null);
     }catch (Exception e){
         promise.reject(e);
         e.printStackTrace();
     }
 }

It looks like this library's removeItem is fixed in Github but npm is not updated.
