Update WordPress tracking commit
Add a wp-content directory to be used as the content directory after installation

First. There are some things in the content directory that should not exist until after WordPress has been installed. We should move them over as they are required during provisioning.

Second. content/ is a crappy name for a directory whose original name is wp-content. We should keep it as wp-content so that sites can be moved to other WordPress installations with minimal effort if the need ever arose.
Move themes directory from content to wp-content
Move plugins directory from content to wp-content
Set the content directory in local-config.php to wp-content
Add a placeholder sunrise.php for use during installation

We'll copy the proper sunrise over after the network is initially setup.
Update .gitignore for the new structure
Merge pull request #4 from washingtonstateuniversity/initial-state-handling

Use wp-content rather than content as the content directory. Set things up for better install via provisioning.
Ignore plugins that are brought into the wp-content directory during provisioning
Remove  from the SITEURL
Remove unrequired index.php and xmlrpc.php files

We're running WordPress in a subdirectory in a way that only uses wp-config.php a level up rather than requiring index.php to be there as well. There really isn't a need to have these files as our nginx configuration points to index.php inside the `wordpress` directory and these will never be hit.
Ignore–at least temporarily–the wp-content mu-plugins directory in version control
Don'y check for multi network in wp_get_networks()

This can still return the current (single) network in a standard multisite installation
Ignore the uploads directory
Merge remote-tracking branch 'remotes/origin/wsu-co-authors-plus-skin' into wsu-co-authors-plus-skin
Move Co Authors Plus skin files to new structure
