implement `crypto.cc` with OpenSSL + fix config loading

  I considered reversing the original `vlong` implementation but
OpenSSL is just simpler, more secure, and most importantly, is
already there. I also made it so the key is now stored in a PEM
file (`tibia.pem`) so it can be easily swapped without re-compiling.

  This was the last piece to build and run a working executable,
except that we now need to implement a query manager for the server
to communicate with. I was able to fix a small problem with loading
the config before hitting the problem with the query manager, which
was expected.

  The next task should be getting a query manager up and running
before starting phase two of upgrading and fixing the server itself.
