File drop callback is incorrectly referred to as dragging

[haykam821]

The Screen#filesDragged method is wrongly named, as it is called upon the dropping of files onto the window as opposed to the initial drag of files. This issue can be seen in the Mouse#onFilesDropped method:

private void onFilesDropped(long window, List<Path> paths, int invalidFilesCount) {
	this.client.getInactivityFpsLimiter().onInput();
	if (this.client.currentScreen != null) {
		this.client.currentScreen.filesDragged(paths);
	}

	if (invalidFilesCount > 0) {
		SystemToast.addFileDropFailure(this.client, invalidFilesCount);
	}
}
