Command-output tooltip execution spam

[trigg]

When a command_output_tooltip_* key is used we get excessive calling of the command on mouseovers.

wf-shell/src/panel/widgets/command-output.cpp

Line 131 in 3e7576f

signal_query_tooltip().connect([=] (int, int, bool,

The signal_query_tooltip callback is called for all mouse movement over the widget.

The tooltip's content is updated only once a second though

wf-shell/src/panel/widgets/command-output.cpp

Lines 117 to 125 in 3e7576f

	const auto update_tooltip = [=]
	{
	if (std::time(nullptr) - last_tooltip_update < 1)
	{
	return;
	}
	label_set_from_command(tooltip_command, tooltip_label);
	};

What I'd like to see is, the tooltip updated at $interval while it's open, as the button data is.
