* Set pcre.recursion_limit, 3x the limit necessary to process a valid 253 character domain name
* Updated validate_domain() to include underscore as a valid character within a domain
* Run escapeshellarg() on `pihole -q` command in the unlikely event that a maliciously crafted domain query is able to pass validate_domain()
* Known issues: Changes to the output of this file and Pi-hole core's queryFunc() results in `queryads.js` failing to work (Thereby breaking Tools > Query adlists)
* Move whole project to EUPL, copy MIT license to scripts/vendor/ and style/vendor/
* Added header to main PHP files
* Modified scripts in scripts/pi-hole/php
* Added header to scripts/pi-hole/js files
* Added license header to our custom style script
* Slight reformulation
