ignore zero-length lines that are part of some font files (prevents problems with Polygon objects)

added support for "reverse" arcs in font definitions

* a pstoedit bug in Ubuntu 'lucid' causes a non-zero return code for the eps->dxf conversion
* this exit code (-11) is accepted with a warning now

fixed the generation of the triangle's normal (in case they are undefined or badly formatted) during import (they pointed at the inside of the model before)
fixed the order of vertices when creating a new Triangle instance (clockwise instead of STL's counter-clockwise order is expected)
output a warning once if the direction of the normal does not match the order of the vertices of a triangle (both indicators are redundant and should be consistent)

 * otherwise they are currently not transformed
 * this increases memory usage slightly, but avoids out-dated edge information

more verbose output of the DXFImporter

added a "unit" parameter to the importers -> the svg/dxf importers can re-scale the model now, if the user configured "mm" instead of "inch" (pstoedit seems to output scaled to inch)

 * fixes performance issue when using a support grid (previously a new (non-kdtree) trimesh model was created)
implemented a proper update-trigger for kdtree of trimesh model
