NLTK's Vader version doesn't support sentiments of emoji's

[cjhutto]

The NLTK administrators may not keep their vader module as up to date (or maybe not as quickly as I make updates to vaderSentiment). This repo will always have the latest version, and I push regularly to PyPi (so pip install upgrade vaderSentiment should work to get you the latest, most of the time, with maybe just a little lag behind this repo).

Could not find a version that satisfies the requirement upgrade (from versions: )

@cjhutto - Emoji's seem to be only outputting neutral score as if it's not taking it into account emojis. Please find reproducible steps below:

1. In terminal: pip install --upgrade vaderSentiment
2. In Jupyter notebook:

[cjhutto]

So, NLTK lags PyPi (pip), which lags this repo...

If you use
pip install --upgrade vaderSentiment
then make sure to import that version instead of the one from NLTK, e.g.,

from vaderSentiment import SentimentIntensityAnalyzer
vader = SentimentIntensityAnalyzer()
print(vader.polarity_scores("💋 and 😁 "))

{'neg': 0.0, 'neu': 0.508, 'pos': 0.492, 'compound': 0.7003}

@cjhutto What can I do to use newly added emojis?
As you can see below, sentence 2 and 3 have the same score, so seems like it is not recognizing the second emoji in sentence 3.
