Cedar/Command: add "limit_range" parameter to StrToPortList()

Browse Source 
Originally, StrToPortList() returned NULL when it encountered a number equal to 0 or higher than 65535.

This commit adds a new parameter to the function called "limit_range":

- When its value is true, the function retains the original behavior.
- When its value is false, the function doesn't check whether the number is in the network port number range (1-65535).

The change is required because the command to set the UDP ports will allow to remove all ports by specifying "0" as the port number.
