Adding a gas material object crashes the app

[samuelduchesne]

Hi @rosecodym, I was playing around with the editor and realized that adding a new gas material (Add component button) crashes the app with error: System.ArgumentException: 'Property set method not found.' at line 84 in this loop:

basilisk/LibraryEditor/ViewModels/ActionBarViewModel.cs

Lines 78 to 86 in 30506ea

	foreach (var prop in type.GetProperties())
	{
	object def;
	if (localDefaults.TryGetValue(prop.Name, out def) ||
	sourceDefaults.TryGetValue(prop.Name, out def))
	{
	prop.SetValue(newComponent, def);
	}
	}
