Disables the 'create transfer order' button in the unit transfer dialog if no units are actually selected for transfer (including when the dialog is first loaded).
This really needs to be a proper type, but this is a start: create new
categories for the types of TGOs that are missing. This removes some
icon special cases.
Many of the schema version increases are just to add new features that
don't render old campaigns obsolete. Convert the version number to a
major/minor format so we can detect the difference between changes that
render old campaigns obsolete (major versions) and new features that
will not work on older builds of Liberation (minor versions).
Loadout selection no longer has two (disagreeing) implementations. What
the UI shows is now what the miz will have.
We now store the chosen layout in the Flight *always*, not just for
custom loadouts. This means that we do loadout lookups at the start of
each turn, but the data is cached in pydcs.
Era-specific loadout degradation is still done at generation (and
presentation) time. This is so that players can toggle that option and
have it affect the *current* turn, rather than the next one.
This is a pretty janky system until we get add context menu support. For
now the destination is set by dragging the CV marker and cleared by
right clicking the destination marker. Once we have a context menu a
context action will begin setting the destination the way it did in the
old UI, and the destination marker will be draggable.
These are an implementation quirk, and passing them to the UI just means
that we put TGO pins on top of the CP, which makes the base menu
unopenable.
In the old UI we avoided this by not drawing anything that was
`for_airbase`, but now that we can zoom in further we're drawing base
defenses.
To avoid confusion, use only the aircraft list for the purchasable
aircraft. This fix also caught a faction's Tu-142 that was not actually
purchasable. Invalid aircraft in the faction aircraft list will now
raise an error.

For whatever reason this only shows up in packaged builds for us, and
also the recommended workaround of using a member property rather than a
decorated method does not work for us.
Until PySide2 5.15.3 (or later) is released, we need to use a named
signal for every property we expose.
