- Fixes the broken population logging

- The current, file-based ban system is now a legacy system, the use of which is strongly discouraged for servers, which are constantly online.
- Added a database-based banning system, with a new baning panel, accessible through the 'banning panel' verb. Servers, which use this new banning system, will get the new panel up even if they use the old 'unban panel' or 'display job bans' verbs. These remain there for legacy support purposes. (Panel screenshot below)
- The most notable benefits of the new system are the ability to add offline bans, meaning the person does not have to be connected for a ban to be applied to their name. The second benefit is the ability to look up all previous bans that the person had.
- The major disadvantage is the complete incompatibility between the old and new system, meaning you have to either do a lot of copy-pasting or playing around in code to sync the old system with the new one. Servers upgrading to this system might want to consider a purge of all bans, if they don't want to go through this. Due to the incompatibility, there are no transition tools provided. Please contact me (errorage/rageroro) in #coderbus for help in syncing your database. The /tg/ legacy and database systems have been synced.
- The server configuration defaults to use the legacy system, as the new one requires the database to be set up. Please hash BAN_LEGACY_SYSTEM in config.txt as explained, to use the new system. If the database connection fails, the server reverts to the legacy system.

If any bugs or errors appear with either the legacy or new ban system, please let me know ASAP. The same applies if there are any syncronization problems between the legacy and new system, resulting in banned people unbanned or unbanned people banned.
