config: return an emtpy string when there is no value
Returning NULL for the string when we haven't signaled an error condition is counter-intuitive and causes unnecessary edge cases. Return an empty string when asking for a string value for a configuration variable such as '[section] var' to avoid these edge cases. If the distinction between no value and an empty value is needed, this can be retrieved from the entry directly. As a side-effect, this change stops the int parsing functions from segfaulting on such a variable.
