Added a built-in "amx_nick" command that can be used to change player names. Aliases: "amx_nick", "nnc_name" and "nnc_nick". Its purpose is to overwrite the original command from AMXX so it can work properly without needing to edit it.
Added a cvar "nnc_show_message" that controls whether a message will show in chat when a player is denied name change.
Added a cvar "nnc_dead_immediate" that can make name change for dead players take effect immediately instead of when the player spawn.
Cvar changes now take effect immediately instead of on the next map.
The ReAPI version has been canceled since it only makes future updates more complicated without any real benefit.
