Scene browser progress

Well, made some more progress on the scene browser. I've got the types section working now.

This will be the section that allows you to work with sets of objects based on their types, like "hide all curves", "isolate all solids", etc...




There are also 2 sub-sections within it, "Selected", and "Unselected", which allow you to target all objects of a specific type that are also currently selected or unselected.



That allows for some pretty detailed kinds of filtering involving the selection, things like "isolate only the curves from the current mixed selection".

In the future there can be some other sub-sections in here like "Locked" and "Unlocked", to enable things like "Hide all locked objects" really easily.
