Tyler Denniston dada960d79 [svg] Add feTurbulence filter (incomplete)
This was the simplest one to start with. I need to add support for the
"filter effect subregion" in order to handle tile stitching property,
so this isn't quite complete. But I believe this is enough for the
basic filters-turb-01-f test to pass, which gives us a baseline for
further filter work.

Summary of changes:
- Added attribute type and parsing for SVG integer datatype
- Added new node class for feTurbulence
- Added several new properties and parsing for feTurbulence
