Str2I64() octal prefix 0o

Browse source 
* Comment at top of function hints that 0o18 is treated as an octal number but it is not
* Adding the appropriate switch-case makes it work by adjusting radix
* Update comment: this function is more like strtol() because it returns a signed result
* This function doesn't behave like strtol() because "0" prefix can't be used for octal, e.g. "0777" (maybe it could be supported in future)
