When local aircraft scanning is slow, we can end up clearing
the locale while a scan is in progress, which crashes. Ensure we
abandon any in-progress scan when closing the launcher.

Avoid filling up the logs when the launcher parses broken aircraft XML;
wait until the user actually pick one to fly with, before reporting
XML errors.
Fix the include context when -set.xml are parsed by the launcher to
extract states and other data. Ensure aircraft paths are available
and handled consistently with normal -set.xml parsing. Without this,
many -set.xmls fail to parse.

Lars T identified some cases where the launcher would fail to include
local aircraft due to them using weird ways to include additional
XML into their -set.xml. Add a temporary resource provider while the
launcher is scanning, to make this work.
Will pick to LTS branch once verified.
The HistoryPopup was caching its contents rather early, and we failed
to tell the model when its underlying data updated. Connect that
through so the history model refreshes also.
