Add defaultValue arg to get*Value() methods that previously took no args. We do this for getBoolValue(), getIntValue(), getLongValue(), getFloatValue() and getDoubleValue(). The default value is returned if the node's string is not convertible to the requested type. This can enable some calling code to be optimised where it previously checked for getStringValue() (which is slow now that it returns a std::string) returning an empty string, before calling getDoubleValue().
