Toast timeout violation warnings

[dl3sdo]

In mobile mode there are developer warnings: Minimum toast timeout is 500, got: 0
The reason for that warnings is that MainWindow::autosave() and MapEditorController::loadFrom() call MainWindow::showStatusBarMessageImmediately() (which will call MainWindow::showStatusBarMessage) with an effective value of 0 for the timeout parameter.

While this is not an issue in desktop mode, in mobile mode toast->showText(text, timeout); will be called which will trigger Toast::startTimer().
There the timeout value is checked to be between 500ms and 5000ms. Values below will become 500ms and values above will become 5000ms. In addition a warning is issued as this is not the expected behaviour.
In mobile mode warnings are triggered when autosaving the map (a failure would lead to a timeout value of 6000ms) and when loading templates after loading the map.

This would avoid the warnings:

void Toast::showText(const QString& text, int timeout)
{
	label->setText(text);
	adjustSize();
	if (!isWindow())
		adjustPosition(window()->frameGeometry());
	show();
	raise();
	startTimer(qBound(min_timeout, timeout, max_timeout));
}
