Fixed ConVar/ServerCommand registration conflicts.
Fixed Client/Say/Server commands decorators from raising on unload when no callback was registered. Remove the public/private hack. Fixed server commands from potentially unregistering overrides rather than themselves. Added the ability to override convars as server commands and prevent their assignment from the console. Fixed memory leak for new convars allocated by the interpreter. Fixed execute_server_command, queue_server_command and insert_server_command being executed with an extra empty space.
