Title: check url safety

Hey !

I added & implement [safe-url-input-checker](https://github.com/w3c/safe-url-input-checker) to check url safety (loopback, private, localhost, blacklisted websites...).
If necessary we can pass a list of acceptable protocols & a blacklist in options.
tests passed with mocha.

Let me know if you have some questions or comments. :)
