Here's a patch that refactors many of the OS X customizations in IDLE based on more granular criteria, e.g. those that should apply to all Tk implementations vs those that depend on specific ones (Cocoa Tk, Carbon Tk, or X11 Tk) rather than the bogus current framework test.  This should fix the specific problem of the control-click menu not appearing in non-framework builds along with various other issues such as missing menu items when using an X11 Tk on OS X.  It does not address the issue of providing the OS X specific key set with a non-framework build: Issue20580 addresses that.
