Make: use npm update for devel target
package.json says we want coffee-script >= 1.6.1, so that's what `make devel`
should install (the newest version): since .js source is tracked, there's no
risk of running into breaking changes in coffee-script outside of test
environment. But running into such changes during tests is OK and even
potentially desirable.
