Add License README badge to repos

https://img.shields.io/badge/license-MIT-blue.svg?style=flat-square

For example, for PDX we would do:
[![LICENSE](https://img.shields.io/badge/license-MIT-blue.svg?style=flat-square)](./LICENSE)

... which yields ...

@ruebot: me again. I'm so sorry, but I think I messed up all the links because I just copied "https://packagist.org/packages/islandora/PDX" but the "PDX" bit should be replaced with whatever repository I'm working on, right?

[ruebot]

@sowla correct! It should actually be [![LICENSE](https://img.shields.io/badge/license-MIT-blue.svg?style=flat-square)](./LICENSE), which I just updated.

[sowla]

Ah, thanks! Adding new commits now :)

[ruebot]

@sowla great, thanks a bunch!

[sowla]

Thank you too for teaching me! I think I'm done now, hope I didn't miss anything :)

[ruebot]

Awesome! I'll go through and review, and merge if we're all good.
