[API Break] .sequence() and .chainify() now handle multiple `.fulfill()` arguments correctly

[AJ ONeal]

API docs have been updated on github.

Whine about it now or forever hold your peace. Suggestions welcome. This change 

Futures.sequence

This change removes functionality that was most likely not even used and makes it more useable with nodejs, etc.
For many users this requires no change to code (since `index` and `arr` were fairly useless in the first place)

WAS

Futures.sequence(function (fulfill) {

    fulfill("one argument");

  })

  .then(function (fulfill, result, index, arr) {

    // do stuff

  });

NOW

Futures.sequence(function (fulfill) {

    fulfill("one", "two", "three");

  }).then(function (fulfill, one, two, three) {

    // one === "one"

    // two === "two"

    // three === "three"

  });

Futures.chainify

A one-liner fixes old code

WAS

Futures.chainify(providers, {

  consumer1: function (data, params) {

    // do stuff with `data`

  }

})

NOW

Futures.chainify(providers, {

  consumer1: function (results, params) {

    var data = results[0];

    // do stuff with `data`

  }

})
