Delete Standard Accelerator Keys page

The page is not linked to, and therefore probably not used much.
In addition, the mentioned technologies (CDE) and the mentioned Microsoft
book (which is out of print) make it look dated. Overall I think
the benefit of having such a list in our documentation is minor.

-    \title Standard Accelerator Keys
-    \brief Recommended accelerator keys.
-
-    \ingroup best-practices
-
-    Applications invariably need to define accelerator keys for actions.
-    Qt fully supports accelerators, for example with QShortcut. Platform
-    defaults for key bindings can also be assigned using QKeySequence::StandardKey.
-
-    Here are Microsoft's recommendations for accelerator keys, with
-    comments about the Open Group's recommendations where they exist
-    and differ. For most commands, the Open Group either has no advice or
-    agrees with Microsoft.
-
-    The emboldened letter plus Alt is Microsoft's recommended choice, and
-    we recommend supporting it. For an Apply button, for example, we
-    recommend QAbstractButton::setText(\link QObject::tr() tr \endlink("&Apply"));
-
-    If you have conflicting commands (e.g. About and Apply buttons in the
-    same dialog), you must decide for yourself.

-    There are also a lot of other keys and actions (that use other
-    modifier keys than Alt). See the Microsoft and The Open Group
-    documentation for details.
