Internationalization

[augustoscher]

I would like to change the language of read more/read less spans inside the card, that is hard coded.

We could add a new prop in Chrono component to let users determine the texts in any language. Ex:

 "locale": {
    "readMoreText": "some text",
    "readLess": "some other text",
    "foo": "bar"
  } 

What do you think about?
