Unify scrollable list code
The goal of this patch set is to eliminate the code duplication caused by copy/paste of the code in the file selector, listbox, and partition list GUI elements. Those classes will now utilize a single GUIScrollList class that will handle rendering and scrolling. Change-Id: I0cb98ab36cf47178296034293435225658c779cd
