Use more conventional MIT license form

[obscurerichard]

I had steered @dcycle towards this license choice (#16) using https://github.com/intel352/vagrant-shell-scripts/blob/master/LICENSE.md as a sample to adapt, however it is formatted unconventionally and the licensee license detector GitHub uses does not identify it properly. So alas, GitHub didn't identify the license as MIT automatically. Sorry about that!

Instead, use a version derived directly from the text in https://opensource.org/license/mit

(also specify the copyright date of original publication per trijezdci's answer to the question Do copyright dates need to be updated?)
