Specify an array of preferred adapters

[lukaszfiszer]

I've added a possibility to pass an array of preferred adapter when creating a new Lawnchair object

var store = new Lawnchair({
  name:'testing', 
  adapter: ['indexed-db', 'webkit-sqlite', 'dom'] }, 
  function(store) {
    // callback
});

Lawnchair will initialize the first installed and valid adapter from the array, independently of the order in with the adapters were loaded. This permits to control fallback adapters much more easily.

This would be extremely helpful for Chrome development, since Chrome has a hard 5MB cap on localStorage but not on IndexedDB, so as far as I can tell it's not possible to use Lawnchair to store more than 5MB in Chrome until this is merged. (Since currently Lawnchair prefers localStorage to IndexedDB, both of which Chrome supports, but only one of which is capped.)

This change makes sense to me, it'd be nice to see it merged.

Please merge this into master. I think anybody using Lawnchair either implements this by own or finds workarounds. This is very helpful in many cases.

@brianleroux Any thoughts on merging this? The diff is only a few lines of code, keeps the API the same, and would be much appreciated by several of us. :)

Awesome! :D
