ReadonlyFieldItem null checks

[zhdiv]

Hi,
ReadonlyFieldItem class require additional null check. Something like:
protected set { valueText.text = value==null ? "Null" : value.ToString(); }
Got error with null reference exception if field is unassigned.

And if it possible do not display null message in console at Window.OnSubmit() if result.type == CompileResult.Type.Success

And of course big thanks for asset.

Sorry for my late reply...
I've fixed the null check, thank you for the suggestion.
This fix will be included in the next release.

Regarding the null output, I want to think more about it because uREPL cannot distinguish below scenarios:

$ var obj = GameObject.Find("Cube");
> null

$ object obj;
> null
$ obj; // user wants to check obj is null or not.
> null
