Returns a string warning message if the Tk version in use appears to
be one known to cause problems with IDLE.
1. Apple Cocoa-based Tk 8.5.7 shipped with Mac OS X 10.6 is unusable.
2. Apple Cocoa-based Tk 8.5.9 in OS X 10.7 and 10.8 is better but
can still crash unexpectedly.

Perform initial OS X customizations if needed.
Called from pyshell.main() after initial calls to Tk()
There are currently three major versions of Tk in use on OS X:
1. Aqua Cocoa Tk (native default since OS X 10.6)
2. Aqua Carbon Tk (original native, 32-bit only, deprecated)
3. X11 (supported by some third-party distributors, deprecated)
There are various differences among the three that affect IDLE
behavior, primarily with menus, mouse key events, and accelerators.
Some one-time customizations are performed here.
Others are dynamically tested throughout idlelib by calls to the
isAquaTk(), isCarbonTk(), isCocoaTk(), isXQuartz() functions which
are initialized here as well.
