update fastText to latest upstream master

[dcsan]

simply updated to their master
https://github.com/facebookresearch/fastText/commits/master

process:

(clone this repo)

git submodule init
git pull --recurse-submodules
cd fastText
git checkout master
git pull
cd ..
git add .
git commit -m "update submodules"

I might make a script to do this if we need to keep track of upstream fastText

Todo:

• Upgrade to use new fastText api(s)
• Adjust and update node-fasttext codebase

does this update will ever reach master?
