Feature Request. Add in EEschema PCBNew ability to draw simple lines and arrows

[Anton]

Now in eeschema and pcbnew there is an opportunity to draw only rectangles with a dashed line. Always bend is obtained only at 90 degrees. It would be nice to add the ability to bend to a free angle (using the Ctrl key only 90 degrees). Choice: Spline or dashed line. This will allow putting down the directions of the currents to indicate where and on which nodes which voltage (supposed) will make commenting the circuit more visual.
