dlgQNH.cpp: separate QNH out of Basic Setup

This leaves Basic Setup dialog for Bugs & Ballast
dlgPlanes.cpp: remove annoying extra confirmation popup

We don't need two popups messages to do one action that can
be easily undone.
TaskStore.cpp: include .cup files by default.

"More" button will add .IGC files.  Theory is that users may have lots of IGC files
with tasks embedded that the user does not normally want to see.  But, that
users may export .CUP files with tasks they make in CU that are what they
like to use in XCSoar.
dlgPlanes - simplify logic on activate

also make prompts consistent with two paths to activate plane
ZoomButton.cpp: refactor ZoomInButton & ZoomOutButton

Use common ZoomButton
Switch to icons
ExpandMacros.cpp: change On/Off to Show/Hide for terrain etc

change to "Show/Hide" Terrain, Show/Hide Topo,
Show/Hide airspace
dlgStartupAssistant.cpp: new dialog shown at startup with tips

stores the last tip shown and cycles each startup
allows user to suppress future tips
MapItemListDialog - Set button label to "Drag" if target task is selected
MapItemListDialog.cpp: if only 1 item in list, skip list

Simply show the item details screen if only one is in the list.
This ignores items that have not detail screen.
InputEventsMap.cpp: remove "Auto zoom off" message when setting zoom

This is annoying.  We still leave the messages when the user toggles
the auto zoom with the menu.  But when the user zooms the map,
he should know that Auto Zoom is off and not need this message.
GlueMapWindowOverlays: add MapScale back in

But don't show auto zoom
dlgWaypointInfoWidget.cpp: reorganize screen

order: distance, bearing, altitudes, elevation, sunset, comment
SafetyFactorsConfigPanel.cpp: remove Safety MC option

Leave the architecture in tact, but hard code to 0
Also set ReachMode to TASK and remove the
ReachMode option in RoutConfigPanel.cpp
dlgConfiguration.cpp: always start with Expert=false

The idea is to hone the system so users don't need the
expert options.  While we're not there yet, in the future the
expert options will become less important.  Now, tune the
interface to users who aren't experts.
dlgConfiguration.cpp: remove Vario configuration page
LayoutConfigPanel.cpp: remove InfoBox Border Style option

LayoutConfigPanel.cpp: remove DialogStyle setting

Hard code to default (FullWidth)
InterfaceConfigPanel.cpp: remove TextInputStyle option

SymbolsConfigPanel.cpp: remove aircraft symbol

hard code to SimpleLarge
