SVG format fixes:

- Fixed silly error caused by copy-pasteing code from class
  (accessing to self from simple function)
- Fix for illustrator path format -- it doesn't place spaces before
  "minus" sign of next number. Maybe it's time to go out from stypid
  string replacement-splitting to slower but smarter token parser?
