Whenever resolving a (relative) path to an absolute path with
'resolve_maybe_aircraft_path', check if the result is empty and report original
(relative) path as missing. Otherwise no or a meaningless message is
issued ("File '' not found.").
--ai-scenario=... can only add/enable another scenario.
Introduce --disable-ai-scenarios option to disable all scenarios (can be
used by external launchers, GUIs etc)
Also provide error instead of debug message when a scenario cannot be loaded.
Fixed ugly sim-reset issue: Persistent properties (USERARCHIVE attribute)
are retained across sim sessions (when restarting the sim). So they should
also be retained on sim-resets (without the need to first exit/restart
the sim to make them really persistent).
Also, avoid warning due to read-only properties.
Seems the hack was necessary for the pre-OSG display only. Or the feature
is broken since OSG port altogether. But it caused issues for 3D and 2D
cockpits when /sim/virtual-cockpit wasn't enabled. => Removing for now.
Original property-rules in keyboard.xml toggled master and clock freeze
independently - which caused issues when only one property was true. New
command toggles both properties consistently.
This reverts commit b36b33f716.
See #316: Caused issues with sky becoming black in dense fog.
Also: when the fog issue is solved, we could configure the constant
(black) clear color once only (during init), no need to do it in every
loop. Also, entire "if (skyblend) { ... } else {..}" was redundant,
since "if" and "else" clauses were all identical - and the "clearColor"
variables were unused. => Once the fog issue is solved, we can easily
improve the clearColor configuration here.
This class and their source files visual_enviro.[h|c]xx were
unused since OSG transition. It's only functionality was to
keep a variable for the enable-state of rendering of precipitation.
This has now been moved to SGPrecipitation.
This patch also removes all references to this class and
visual_enviro.hxx. Wxradar needs a new implementation for cloud
echoes which probably should be part of fgclouds.

New module contributed: AV400WSim.
Supports communication with external (aka real) Garmin 400/500 WAAS flight
sim units. Includes changes to options.cxx and fg_io.cxx to support
invoking and configuring the new module.
New "auto-position" switch to always use closest tower for tower-view.
Exposes new "/sim/airport/closest-airport-id" property.
Display closest airport on groundradar by default.
