ngram support

The program will automatically download ngram while the app is running. (see languagetool.sh) Depending on the download speed of Heroku & upload speed of LanguageTool's server, ngram will take a while until it is used. As Heroku file system is ephemeral, once the app is restarted, the ngram will be deleted and will be downloaded again on next start.
