Increasing js-schema dependency version to avoid undef error during package require

Hi!  I'm new to node.js, so forgive me if I'm just missing something obvious ...
I had to increment the js-schema version number to get the generate package to work for me.  Before the change I was seeing this:

    > require('generate')
    TypeError: Cannot read property 'patterns' of undefined
        at Object.<anonymous> (/Users/phil/generate.js/generate.js/lib/pattern/reference.js:1:105)
