Change G26 circle angles

Browse Source 
Changed the start- and end-angles for circles in the mesh-validation-pattern to avoid crossing lines.

At the start-/end-point of the circles there is a small dot of filament on my printer.
When drawing lines after the circles the nozzle crashes into those dots and destroys the circles.
I solved this problem by rotating the start- and end-points by 45 degrees.
