Allow page up/down on LEFT/RIGHT in some wizard screens

[prl]

Wizard screens that use <listentry>, <list type="dynamic" .../> & <list type="config" .../> don't allow paging up/down using LEFT/RIGHT when the selections are displayed as menu lists, rather than as ConfigSelection or ConfigBoolean selection list entries.

Some other menu lists in wizards (like IniTerrestrialLocation) allow paging.

This is simple to add, and there doesn’t seem to be a good reason not to.

Fix issue #759: Allow page up/down on LEFT/RIGHT in some wizard screens

[Wizard]

Add code to methods left() and right() to page up/down in setup screens that use <listentry>, <list type="dynamic" .../> or <list type="config" .../> (i.e. screens that create "evaluatedlist" menu lists.

The code parallels the existing code in methods up() & down().

Fix issue #759: Code cleanup

[Wizard]

Remove some lod commented-out code in the up()/down()/right()/left() and move repeated the if "onselect" in ...: block in those methods and in selChanged() into a new doOnselect() method.
