Bug 5962: Keyboard shortcut (Alt+E) fails for series slot with expression [2]
Bug Number: 5962
Release notes (y/n): Yes
For Release Nums: 7.0.8 and 7.1

We've revisited this change.  Instead of taking away the underlined "E" in 
the Edit menu (for only Series Slots with RPL Expression) (but leaving it 
for ordinary Series Slots) we made this change.

  OLD:  Expression >> Evaluate (Alt+E)
  NEW:  Expression >> Evaluate (F9)

(Note that F9 supports "evaluation" functions in MS Excel).

This change effects BOTH of these types of Open Slot Dialogs:

    Series Slot with Expression
    Scalar Slot with Expression

See the change in QtRpl/RplExpressionMenu.cpp, in the RplExpressionMenu 
constructor.  The prior change in Q3GUI/SlotQtDlg.cpp in method SlotQtDlg::
buildMenus() is being reverted.
