Possible fix for #174 and #175 plus minor improvements to TypeSelectionPopupWindow

[SugoiDev]

This might be enough to fix both #174 and #175.

By default, if the user has set the TypeSelectionDefaultFilters using the fiSettings system, a toggle will show (enabled by default) that filters the results on both the StaticsInspectorWindow and any TypeSelectionPopupWindow.

If the TypeSelectionDefaultFilters is not set, the toggle will not be shown.

Since I was already playing with this, I went and added two little extra features

• a little counter for how many types are in display in the TypeSelectionPopupWindow. It lags behind to display the first time around, but should be simple to fix later if necessary

• an (optional) global blacklist for the TypeSelectionPopupWindow so the user can easily hide all those crazy internal types from third party libraries. Again, this will only be used if set.

I bundled those commits into this pull request like this because I'm out of my workstation and had to commit directly using github's editor.

Let me know if I should separate this into multiple pull requests.

Added the same filtering idea from the TypeSelectionPopupWindow to the ViewAllSceneObjectsEditorWindow

Very useful for long hierarchies.

Separated this in #183
