[lmi] Input-sequence editor testing

[Greg Chicares]

These are in chronological order of discovery, which turns out to be
about the same thing as reverse priority order.

* Repaint lmi tabbed-dialog background when "..." pop-up dialog is moved

  alt-F N I
  "Individual mode"
  "..."
  move the pop-up
  Cancel
Background is not repainted: what was turned from white to gray,
remains gray.

A repaint problem with different symptoms:
  alt-F N I
  "Individual mode"
  "..."
  switch to another application
  switch back
  Cancel
In the portion of the lmi tabbed dialog that was obscured by the other
application, enabled text controls change from white to gray. Cancel
repaints only the portion that was under the "..." dialog.

* Use default keyword in new keyword-only controls

  alt-F N I
  "Individual mode"
  "..."
  choose "until retirement"
Second row, first column: no mode selected. The best choice would be
the 'default_keyword' argument of realize_sequence_string(). Today,
that is hardcoded in these functions:
  Input::RealizePaymentMode()
  RealizeCorporationPaymentMode()
but probably it should be moved into class mode_sequence, e.g. as
in this casual sketch:

     mode_sequence& operator=(std::string const&);

     virtual bool numeric_values_are_allowable() const {return false;}
     virtual bool keyword_values_are_allowable() const {return true;}
+    virtual std::string const default_keyword() const {return "annual";}
     virtual std::map<std::string,std::string> const allowed_keywords() const;
 };

A secondary consequence is that the actions above produce the string
  annual retirement;
but editing that result by re-invoking "..." pops up a dialog with
only one "until maturity" row; the "retirement" breakpoint is lost.

* Cannot reenter "..." with a sequence produced by "..."

  alt-F N I
  "Individual payment"
  "..."
  choose "until age"
  OK
  "..."
messagebox:
  The sequence is invalid and cannot be edited visually.
  Interval [ 55, 56 ) is improper: it ends after the last possible duration.
The default "until age" is 100; 99 would be better, but much better
would be DBDictionary::MaturityAge.

Changing the default would prevent the symptom, but this example
seems to demonstrate a deeper problem. The pop-up exits normally,
changing the sequence-string to
  20000 @100; 0
but then it refuses to edit that string. It seems that validation
upon entering the pop-up is stricter than that performed when
leaving it.

* Pressing "Remove" buttons leads to segfault

  alt-F N I
  "Individual payment"
  "..."
  change "until maturity" to "until age"
  change "until maturity" to "until retirement"
  click the lower "Remove" button
  click the remaining "Remove" button
