Change Zoom Control Icons

[carljbowman]

Overview

Overall these icons are out of sync with the rest of the iconographic system. We'd also like to not overload the magnifying glass icon with too many means: Zoom and Search.

This work coincides with work on the Add Menus (#2101), in which we are adding an addtional menu item to open libraries. This icon will signify search in the form of a magnifying glass
