Implemented the login timer functionality.

If a setting is an integer, Don't require another type to disable it. Instead use 0 or -1, as done on other confit settings

I was following what was written in config.yml

#Number of seconds to wait for a player to be authenticated. If false, disables the timeout

[alejandroliu]

OK, it uses 0 or -1 to disable timeouts.

Type of false: Boolean
Type of 0 or -1: Integer
It would be good to use the same type (Integer)
