[ProGrids] EditorUtility.GetColorFromJson

When ProGrids loads its preferences it tries to parse colors using this function, but if you haven't customized anything the colors are empty strings. This is annoying when debugging because it breaks on the throw inside JsonUtility.FromJson several times every play iteration. It also seems passing an empty string here isn't exceptional but by design. Can you add an early out to avoid this exception for a more pleasant debugging experience?

i.e. change it to

Code (CSharp):

1. internal static Color GetColorFromJson(string json, Color fallback)
2. {
3.     if ( String.IsNullOrEmpty( json ) )
4.         return fallback;
5.        
6.     try
7.     {
8.         return JsonUtility.FromJson<Color>(json);
9.     }
10.     catch
11.     {
12.         return fallback;
13.     }
14. }
15.
