Repairing old symbols can change the look of the schematics.
I've attached some repaired symbols. Would someone say that they will
break existing schematics? The pins are on the same place as before

I think the attached symbols match the spec.
If someone thinks there are errors inside please let me know.

to Ales:
   In this symbols I've changed the pinlabeltextcolor to 9 (text, green)
   instead of 3 (graphic, green). 
   tragesym.py 0.0.2 is still using 3.
