- Adapt to no undo on close in KShortcutsEditor by adding undo where appropriate.
- Add the necessary KShortcutsEditor::save() calls where missing.
Use KActionCollection::setComponentData() as a better replacement for KGlobalAccel::overrideMainComponentData().
- Add setProperty(\"isConfigurationAction\", true) for actions that don't belong to the module modifying them.

This replaces the behavior changes otherwise triggered by KGlobalAccel::overrideMainComponentData().

The most important behavior change is to not register an action as gone when it is destroyed in the configuration module.

It likely still exists in its proper module.
