Please describe the changes in your request. Adds a search functionality in the GUI, accessed from the toolbar. With a resource selected, one can search its descendants for resources with a VirtualAddress matching a specific value or within a range. These are displayed in the search view; each one can be selected as usual, and after going back to the main view, it remains selected.

Anyone you think should look at this, specifically? @rbs-jacob
