GetInt should return default val instead of panic

[FarmerChillax]

In GetInt function should return default value instead of panic

// GetInt parses the expanded value as an int if the key exists.
// If key does not exist or the value cannot be parsed the default
// value is returned. If the value does not fit into an int the
// function panics with an out of range error.
func (p *Properties) GetInt(key string, def int) int {
	v, err := p.getInt64(key)
	if err != nil {
		return def
	}
	return intRangeCheck(key, v)
}
