Internationalization Support

[dcantu96]

Is there any plans for Internationalization support specifically for the title-case package? I could work of this if you don't have time.

Basically I need the same title-case rules to apply for other languages (spanish and portiguese)

You're welcome to open a PR for this. I'm not familiar with those languages to know what the "small words" list should be, but I believe everything else already works.
