Added a README.md file
- Tweaked some conditionals so `coauthors_posts_links` doesn't fall over in a non GO environment.
On new installs the cache option has autoload set to 'no'
- Added a admin ajax endpoint to update existing installs
	- /wp-admin/admin-ajax.php?action=go_local_coauthors_plus_autoload_no
code sniffer tweaks.
Reworked option stuff so the admin ajax stuff isn't needed anymore.
Updated README.md
- Also added notes about the template methods and reverted them to the previous version.
Woops
