added getTranslationsArray() method

[askello]

According to issue #273, it would be great to have a way to retrieve translations in the same structure such as for saving (like fill() method). For example I have a view with a form for updating some of my translatable records. My form fields named en[title], en[description], es[title] and so on. It is easy to store these data (via create() or fill() methods), and they can be easily passed to the view via $input->old() method. But there is no way to retrive and pass translations data to the view directly from translatable model, because their stucture is different. What do you think about it?

The method itself looks good and the feature introduced by it also.
But the unittest is no unittest for me - you test your logic with your copied logic. The assertEquals comparison array should be hard in the test to ensure that the method returns what we expect.
Or you split it in some smaller tests - test existing keys, test every single value etc.

it would be nice if this was also added in 6.* version which is the one compatible with 5.1 LTS

@askello i think the test for this method is flawed! i think you should use the same array to fill the model and then test if it equals with the array returned from getTranslationsArray() method! IMHO

@unitedworx thanks for your feedback. I've fixed the test after merging.
