Some more txt/sql login server synchronization:

- removed the option to specify multiple IPs/subnets for 'ladminallowip'
- removed the @gm command and all associated management code
- removed the 'save unknown packets' code
- removed the lengthy TXT ipban code (which was essentially a copy of what's already handled by the socket layer/packet_athena.conf)
- implemented 'start_limited_time' in SQL (expiration for new accounts)
- applied some missing TXT changes from the last update
