Property Space Attribute

The PropertySpace attribute have the same function as Unity's existing Space attribute, but can be applied anywhere as opposed to just fields.

// PropertySpace and Space attributes are virtually identical...
public int Space;

// ... but the PropertySpace can, as the name suggests, also be applied to properties.
[ShowInInspector, PropertySpace]
public string Property { get; set; }

// You can also control spacing both before and after the PropertySpace attribute.
[PropertySpace(SpaceBefore = 0, SpaceAfter = 60), PropertyOrder(2)]
public int BeforeAndAfter;
