Pcbnew: make the line/arc drawing tool show segment length 

This patch adds functionality to the Pcbnew draw tool to show the dx and
dy of the current segment being drawn if the relative origin (pressing
spacebar) is not already set (i.e. if those coordinates are ( 0, 0 ) ).
You can set the relative origin while using the draw tool by pressing
spacebar. The relative origin is reset on exit of the tool.
