babel-preset-es2015 is deprecated

[stiffroy]

babel-preset-es2015 is deprecated now and says to use babel-preset-env. There was an error when I tried using the VAChat component saying:
'Module build failed: Error: Couldn't find preset "es2015" relative to directory'.
For a temporary fix, I installed 'babel-preset-es2015' and 'babel-preset-stage-2' to make the templates compile. But I think it would be better to have these deprecated packages removed and their updated packages used instead.
