show/hide objects in heirarchy

[tenabraex]

Currently in VSMC you can show and hide objects, but they only show/hide by heirarchy, we want to be able to hide any object regardless what it is, and perhaps for simplicity we might also add a toggle for 'export' here for dummy geometry we want in place for modelling purposes but not in the export (say putting a sword in a models hand when animating it, but you dont want to export the sword with the model.

so we'd have our heirarchy set up with a couple little clickable icons next to each object, an eye icon for show/hide and a whatever icon for export/dont export (similar to how the layer panels in a lot of software do it)
