Add support for ingredients in Italian

[gianantoniopini]

Added first version of ingredients .json files in Italian ('it') and new function to set the ingredients language.
In order to add support for more languages in the future, the ingredients .json files will need to be added under the i18n directory, as already done for 'it'.

Resolves #14

@hmontazeri Can you please have a look at this pull request ?

[hmontazeri]

sure @gianantoniopini as soon as I find a free minute. Thanks for the PR.

[gianantoniopini]

@hmontazeri Hi Hamed, thanks.

[hmontazeri]

@gianantoniopini do we really need the dependency to validate.js?

[gianantoniopini]

@hmontazeri Regarding the dependency to validate.js. Currently it is used in the new setIngredientsLanguage function to perform basic validation when setting a new ingredients language. I thought it might be a good idea to sort of "delegate" the validation to this package. But we could also remove this dependency and implement the validation code ourselves, if you think it might be better.

[hmontazeri]

I’d rather have no dependency to other packages if not really necessary... so I’d recommend we do it ourself as it’s just a basic validation if language is set or not. Do you agree?

[gianantoniopini]

Yes, i understand. I will move the validation implementation to our package and remove the dependency to validate.js . It should be a simple change.
