save best score in localstorage

[getify]

probably have it store the game version with the score, and if the game version has a minor or major change (not just patch), have it reset the best scores to 0

I created a pull request, see #24
I don't know if its the best solution to store the whole data as a string in a single localstorage item. What do you think?

[ntwcklng]

My next approach: ntwcklng@699c33c

I think this is far more better then the previous version.

this looks much better. i'll try to take a closer look soon. :)

The other thing I'd suggest is that there may be other things we want to store/persist than just the score, so maybe there should just be a single data structure that we fill in... like:

settings = {
   "build_version": "...",
   "best_scores": [ 3, 5, 8 ],
   "...": ...
};

In this way, it'll be easier to just add new data to be stored in the future.

Okay, here we go: master...ntwcklng:master
It gets better and better, thank you!

[getify]

Much improved, thanks! There's a few more tweaks I'd like to make to the organization/logic. Would you like to PR this as-is and I can then iterate on it after landing it?

Sure, it's an awesome way to learn! #29
