Updated link to docs
Removed guides directory

Guides directory should not exist in two places now that we’ve merged
it into the wp-api.org site. We want to make sure all the contributions
go to one place.
Updated documentation links in main docs folder

Updated links to point to the wp-api.org site.
Merge branch 'master' of https://github.com/pollyplummer/WP-API into docs-updates

Conflicts:
	docs/guides/getting-started.md
Moved routes docs into 1 file
Fixed broken Getting Started guide link
Added Schema to Routes docs
Removed files that were transferred over to docs

These files are now included in the docs repo and we should not have
two copies.
