Fixed numerical issue with the new algorithm to connect infill lines

Browse source 
with perimeters:
1) Increased accuracy of the contour length parametrization from
   float to double, as double should capture the difference of
   32bit coord_t with full accuracy (or at least very close).
2) The algorithm to insert the T-joint points into the infill perimeter
   contour was improved to avoid inserting duplicate points.
