Votifier-py

Security update*. If you are upgrading from an earlier version, please delete the public and private key files.

*Nothing to worry about: while loading for the first time, VanillaVotifier used to generate 2024-bit keys instead of 2048 ones. Everything still works with 2024-bit keys, and messages are properly encrypted. However, 2024 is just a typo-mix between the two more standard 1024 and 2048-bit encryptions.

Little fix on the private and public key headers, which weren't following the OpenSSL standard.

Improved server restart.

Added license notification on program startup; changed the "reload" command back to "restart"; added more readable error messages insted of some exceptions; improved config loading; improved internal language pack output write speed.

Fixed another little typo.

Added the "info" command to the manual and the command list.
