Title: Cleaned up the treeview expanders to give a crisper look.

The treeview expanders looked very "smudgy" in the current theme due to an imbalance of
the grey colors around them. This commit removes the imbalance and replaces it with clean
transparencies and sharp lines, greatly improving the overall appearance.
