Add PR and deploy process doc to repo

[codemonkey9000]

@keenbrowne and @dariusgarza please let me know if you think this sufficiently covers our bases for QA and deploy process!

Any additions are welcome.

Looks great so far. Maybe add a warning or intro in the deployment section about NEVER touching master, and to treat dev as a psuedo-master.

Would it also be helpful to include "review PR checklist" before deployment?

Think we can add a few bullet points to clarify how to review functionality. Search could say something like: 1. Attempt a search via pressing enter on mobile and desktop, 2. Search via pressing search button on mobile/desktop, etc...

Will update if I think of anything else, Thanks!

Should we also add something like "merge origin/dev into local branch" before asking for a PR and then once again during the PR review?

Let's add this:

npm install broken-link-checker -g
blc —help gives you all of the options but the standard check is blc http://yoursite.com -ro

also, i think line 6 should be blc instead of brc?
