look into WorDBless for testing WPSite or such classes

[leonstafford]

Last regression issue was related to incorrectly parsing/forming URLs and I'm pretty sure there's no test coverage of that class.

WorDBless looks like it can help by setting WP options and then asserting on WPSite's properties and methods.

Test boundaries for URLs and paths, like:

• http
• https
• custom ports
• localhost
• sub.sub.domain
• domain.tld/subdir (expect it to start red)
• win filepaths C:\something\xampp\somedir\
• trailing/non-trailing slashes (do we need to check or does WP force one?)
• filepath with dev site domain within it, ie /var/www/mydomain.com/htdocs
