Added s-r lines and button.

Hull Master 22 Next MTF, HMA nrp alerts + arrows are very interesting. If the High-low trend indicator also adds Add s-r line, it must be interesting.

extern bool LinesVisible = true;

(Because the High-low trend indicator is not a zigzag indicator, it is more interesting than HMA.)
