deprecate magic properties / methods

[tacman]

In my branch I've removed the magic __get and __call methods, and moved what was core into the phpscraper, so now there is only one class.

After a while I got tired of find/replace, so I created a rector rule to change the properties to method.

Is there a demo repository that uses I can use to test my branch? Tests are passing, except for the ones related to internal/external links, which I'll address in another issue.
