Split up monaco's language chunks

This should speed up monaco's loading time by splitting the current
3.71MB chunk monaco.js into 63 individual files named 1 to 63.js in
the output directory. There seems to be no way to get a better file
naming scheme unfortunately. I opted to exclude those files in the
webpack output for brevity.
