Title: [Utilities] Deep copy `null` as `null`. Display object type in varDump

Some minor tweaks to Zotero.Utilities.

I don't think the change to deepCopy should break anything. At least this seems like the more correct behavior. I guess it's a bit odd to single out `null` from all the other possible objects, but `null` is quite special :-)
