Build: Implements GH API to upload binaries

[am11]

This is first in the series of overhauling build steps. Find the related discussion at: #712.

The public access token can be generated from: https://github.com/settings/applications#personal-access-tokens.

Usage:

Anyone with write-access to sass/node-sass can run:

node scripts/upload --auth MyGitHubOAuthToken

This will upload the binary file to the latest release (for instance, current is v2.0.1).

To upload the asset to specific release:

node scripts/upload --auth MyGitHubOAuthToken --tag 2.0.0

To upload the asset from a custom paths:

node scripts/upload --auth MyGitHubOAuthToken --path ~/docs/my_emails/someoneITrust/blah.node

//cc @nschonni, @xzyfer

Thanks @izuzak for help with curl connect (via email). That helped me figuring out how to pass the token and fetch the upload URL!

@callicles, based on the comment on SO FYI. Your answer really helped! 😃

@nschonni, @xzyfer, we can upload the asset to existing release by editing the release.
This script will be useful when were are text-only/CLI-mode in headless CentOS for instance, to build binaries. We don't need to scp to host OS to drag drop in browser. 😎

@am11 glad it could be help full :)

May seem silly, but I'd almost think this should live in the node-sass-binaries repo
