Add freeCap examples

[SavageCore]

This PR adds example for freeCap originally available at puremango blog and can be found in use at http://www.aleph-tec.com/eicar/

I also modified the solve page and now it solves multiple images, validates them, times the process and includes a nice little css loader/spinner so you know it's busy working away.

Note: I do not handle service no longer available but included it in captchas. Seems to be temporary rate limiting.

Let me know if you want me to squash or any other changes needed 😀
