Using locales and translations

[Luisetelo]

I've translated the entire component and now is both available in spanish and english. Here is a list of changes I've made:

• The month day is presented in cardinal according to http://materializecss.com/forms.html
• The first day of the week and day names in the calendar change according to the current locale
• Added external translations for OK and Cancel buttons.

Hi, thanks for the PR! 👍

I don't want to include moment locales here, because many people would have to include code that they don't need in their app bundles.

You can import and use moment locales outside of the component itself - see #89 (comment) for an example with <script> tags. I am pretty sure it works the same with bundled modules.

Could you re-submit the PR without that import, and without the compiled files? I'll have time to review it later this week.

Thanks!

Honestly, I rule out the option of loading moment-with-locales.js for the same reason you mention. However, I didn't find a solution for loading locales dynamically.

I am using your package as part of a Ember component, so I am no able to write <script> tags. Usually material-datetime-picker is used like this:

    const picker = new MaterialDateTimePicker({
      format: 'DD/MM/YYYY HH:mm',
    });

Is there any other way of loading the locales for your package?

CRAZY IDEA: What do you think of receiving the moment object from outside? I use one throughout my code with all the locales that I need...

Closing this PR. I will submit a new PR with an improved version :)
