Automating the creation of the post directory

[GregBorrelly]

I plan to write my posts via PRs, every time I need to add a post, I need to create a post directory, index.md etc. I thought it would be a good idea to automate this to a certain extent. What do you think ?

New Command:
npm run post [post-tile]

Example usage:
npm run post the-latest-and-greatest

this creates a directory inside posts named 2018-11-18--the-latest-and-greatest with an index.md file inside of it containing:

---
title:''
cover:''
author:''
---
