Please rename Slovene stopwords to Slovenian

[PrimozGodec]

Hi, during language refactoring of the orange3-text module, I noticed that NLTK use Slovene as a key to Slovenian stop words. I suggest remaining it to Slovenian. The reasons are the following:

• All other packages that we use also use Slovenian
• Slovenian is the standard name according to ISO standard
• Also main NLTK package references it as Slovenian. Look at this search: https://github.com/search?q=repo%3Anltk%2Fnltk+slovenian&type=code

I know there is a bit of confusion, but since two terms exist for Slovenian, Slovenian is definitely more common. I wanted to make a pull request but didn't find where stopwords are stored.

Any news on this one? Can you please let me know where is it defined, and I can propose a pull request?
