Run jsduck through grunt

* New grunt commands: jsduck, docs
* Replace ruby jsduck with grunt jsduck task

If you're not running jsduck from inside vagrant then you can pass
the MediaWiki install path as an argument so that jsduck is able to find
the Mantle javascript files:
* grunt docs --MW_INSTALL_PATH=/some/path/
* make jsduck MW_INSTALL_PATH=/some/path/
