InspectorUtil fails to load current Inspector window in Unity 2018

[Maclay74]

So, it looks like something is broken in 2018.3 beta.

Everything is working great in Editor, but when you try to Play, initialize error occurs.
Seems like, something goes wrong in Initialize function in Assets\OneLine\OneLine\Editor\Utils\InspectorUtil.cs

So, in order to work around I found useful to check is s_CurrentInspectorWindow really exist and in case of null return false.

So, there are some changes I've made:

       public InspectorUtil() {
            enabled = false;
            if (EditorWindow.focusedWindow is PopupWindow) return; // Detect is it [Expandable] popup

            try {
                if (this.Initialize()) // Additional check
                    enabled = true;
            }
            catch (Exception ex){
                Debug.LogError(INITIALIZATION_ERROR_MESSAGE + ex.ToString());
            }
        }

       private bool Initialize(){
            inspectorWindowType = Type.GetType(INSPECTOR_WINDOW_ASSEMBLY_QUALIFIED_NAME);

            // If this field doesn't exist, return false
            if (inspectorWindowType.GetField("s_CurrentInspectorWindow") != null) {
                window = inspectorWindowType
                .GetField("s_CurrentInspectorWindow", BindingFlags.Public | BindingFlags.Static)
                .GetValue(null);    
            } else {
                return false;
            }
            
            scrollPositionInfo = inspectorWindowType.GetField("m_ScrollPosition");
            getWindowPositionInfo = inspectorWindowType.GetProperty("position", typeof(Rect))
                                                        .GetGetMethod();

            var test = ScrollPosition;
            return true;
        }

I see that new version is coming, hope this issue would be helpful.

Thank you for this bug.

The problem is there:

• in 2017.3, the last I've tested, field s_CurrentInspectorWindow was public;
• in 2018.3b s_CurrentInspectorWindow is internal.

This breaks some reflection magic.
I'll fix it in v0.4.0.
