Allows the Settings > Hotkeys screen to be localised, including hotkey decriptions, groups and contexts.
The hotkey names are exposed to localisation via KeycodeExts. Hotkey modifiers are similarly exposed via ModifersExts.
The Settings > Input screen has a Zoom Modifier dropdown, which shows the localised modifier name.
The --check-yaml utility command is taught to recognise all hotkey translation, so it can validate their usage.
The terms "width" and "height" are clearer and they match what the values actually represent (window or parent width/height). The YAML changes are generated with the update rule.
PARENT_TOP and PARENT_LEFT should be 0 so they are not very useful substitutions. They are replaced with 0 or removed if that was the whole value for a field.
- Increase space of some elements to fit their text.
- Remove editor text that aren't translation keys. The text will be set in code anyway.
- Remove some unused elements.
- Provide a translation key for the port separator, to avoid log warnings.
If you edit an actor name, then delete the actor - it fails to be removed from the map in the editor. This is because the actor previews are keyed by ID. Editing their name edits their ID and breaks the stability of their hash code. This unstable hash code means the preview will now fail to be removed from collections, even though it's the "same" object.
Fix this by making the ID immutable to ensure hash stability - this means that a preview can be added and removed from collections successfully. Now when we edit the ID in the UI, we can't update the ID in place on the preview. Instead we must generate a new preview with the correct ID and swap it with the preview currently in use.
Some existing widget are too small to accommodate their text. Adjust their sizes to fit. Text can be rendered outside the widget bounds so visually this often has no impact, but adjusting this now will help in the future for checking translation text for other languages fit in their widgets.
