Add a class TOOL_MENU, which provides a management class for a CONDITIONAL_MENU and a set of CONTEXT_MENUs. The aim of this is to provide a central place where all TOOL_INTERACTIVEs can get a "basic" context menu that either they or other tools can register new items and sub-menus against. This means that "top-level" tools no longer need to manage the lifetimes of any CONTEXT_MENUs that they add, and can also delegate simple menu display functions.
