Combined two versions for a version that sorta exports stars and does shallow clones

[RollingStar]

This is based on the code that RomaniukVadim tweaked (uncredited from this repo). The benefits are

• sets username and token as globals
• provides link to https://github.com/${name}/archive/master.tar.gz (easy to tweak to tar.gz export)
• shallow clone (depth 100) for stars
• avoids SSH (no need to create a public key)

I did shallow clone to get around huge repos with years of history. Not saying this is great code, but sharing it in case someone else finds it useful.
