DHC6: simplifying the gui structure a bit

Pup 0.26.1: Correct mistakes in htail and vtail areas

* Regenerate aerodynamics with Aeromatic++
* Re-tune drag for quoted performance
* Add tuning coefficients

Checklist update

Saab37 - Version 4.009
GUI: Added 3 thumbnails for new launcher in FG 2017.1.1
Control: Made pitch control be normal based, as per diagrams of real Viggen FCS.
Sim: Blackout code now respect default blackout if FG version is 2017.1.0 or larger.
Sim: Increased G to 8, before FG complains that you are overpulling Gs. Negative set to -2.
Sim: Tuned altitude A/P.
Effect: Wingtip vapour is now from canards.

Pup 0.26.0: Major FDM rework

* Aerodynamics regenerated with Aeromatic++ 3.3.8
* Propellers modelled with JavaProp for correct pitch and static RPM
* Drag tuned to match quoted TAS at various altitude and RPM
* Engines tuned to match quoted fuel flows and static RPM
* Instruments adjusted to engine limits
* Analysis and tuning configuration added to FDM
* Other FDM tuning (ground reactions, CoG, AeroRP)

Pup 0.25.2: Keyboard shortcuts

* Add shortcut to run before takeoff checklist
* Add altitude hold shortcut
* Remove cruise power shortcut

Pup 0.25.1: Prevent stall warning firing when changing views

Pup 0.25.0: Add stall warning sound

Only based on published stall speeds at this stage, rather than AoA.

Pup 0.24.0: Refine checklists against real aircraft procedures

* Checklist steps now reflect most of real procedures
* Alternator light is a warning light for not charging/low RPM
* More protection against autostart failures
