updates to setup of Stryker Mutator (#272)

* renamed `stryker` scripts entry in `package.json`

* split `mutate` configuration into multiple lines in `stryker.conf.js`

* split `reporters` configuration into multiple lines in `stryker.conf.js`

* TBD commented out for now: add `bin/**/*.js` to mutate configuration

in `stryker.conf.js`

(there seems to be an issue with Stryker mutation testing on `bin/*.js`)
