io_raw_mesh: fixes,.. already were done but gone 'lost' (no svn history, nothing in patch tracker,...). wtf?!?

add support for single or multiple uv textures. fixed material id. Deal with faces assign to an materials.

- Fixed incorrect usage of 255 color range -- each component should
  be from segment [0..1]
- Added "style" tag parsing

Just required some misc updates due to python API changes.

zero length bones had their tail offset in the wrong direction.

Only <path> is supported at this moment, other geometries would
be added a bit later. Transform attribute, defined, groups and
uses should work pretty fine.

Work is in progress, so please repoer issues to me, not to tracker :)

alpha layer if this layer is unmodified (pure white) even if the layer

checking if the alpha file exists or not
