I realize ChromeStoreLaunchURL() is already an example of this, but this method
has nothing to do with the Extension class. Maybe this should go in
extension_constants?

Also, the naming should be GetChromeStore...

Moved to extension_constants and renamed to
GetWebstoreLaunchURL/GetWebstoreItemDetailURLPrefix.
