Composer install does not come with built files

[panzarino]

When Chart.js is installed with composer, the built files are not included. The only thing installed is the master of a tagged release.

Is there a way to possibly set composer to use the npm release (like what we do with bower)? Do we want to completely drop official support for composer because of the new release system?

As far as I know, Composer is not nearly as popular as any of the other distribution options for installing Chart.js, and users would still be able to install older releases of Chart.js even when new support is dropped.

Also, the package is listed on composer as nnnick/chartjs which could (and should) be updated to chartjs/chartjs if we choose to keep support.
