Rename control commands

Could we rename the following commands? For the sake of brevity and clarity:

typedef enum {
    NORNSCTL_COMMAND_PING = 1000,    // rename to NORNSCTL_CMD_PING
    NORNSCTL_COMMAND_PAUSE_ACCEPT,   // rename to NORNSCTL_CMD_STOP_LISTENING
    NORNSCTL_COMMAND_RESUME_ACCEPT,  // rename to NORNSCTL_CMD_RESUME_LISTENING
    NORNSCTL_COMMAND_SHUTDOWN,       // rename to NORNSCTL_CMD_SHUTDOWN
} nornsctl_command_t;
