Feature: Reimagine token system

Is your feature request related to a problem? Please describe.
Access tokens was and is the base of Quark security system, but the token table must have some security improvements though.

Describe the solution you'd like
In Quark Server, the tokens was not encrypted at all. It means that anyone who gained access to the file system could just take the tokens for free. To prevent this, the tokens must be encrypted and salted.

• Create the system database, where the tokens table will be stored. Ensure it's created if does not exist on start-up;
• Create the tokens table inside of it.
• Update corresponding token functions of creating tokens, applying hash on it and salting them.
