Release/v0.0.9

Updated normal map Y-invert code so that the node group does not get created again if it already existed.

Changed texture import so that original nif texture path is preserved if file is not found, allowing re-export with working textures.

Added default NONE game for in the scene tab, and a comprehensive error when they forget to set the game.

Changed collision layer to be game dependent, rather than relying on Oblivion collision layers. No Skyrim functionality - best fix for that would be pyffi/nif.xml update.

Updated documentation for export. Moved custom anchors to above titles, so that they will use title text without needing custim link text. Updated spelling of vertex colour to american for consistency.

Implemented PR review comments from Hendrix: Renamed variables xxxlist in export/geometry/mesh. Pulled normalization of imported normals out to separate function. Use ndarray.asbytes() instead of struct.pack() for conversion to binary data.

Updated code as per PR review. Pulled game out to local variable, renamed nr_vertices to num_vertices and renamed argument as_extra to as_extra_data.

Refactored so that the to_tuple() conversion and normalization is done only once per vertex, instead of first copying to all loops and then normalizing it independently multiple times.

Fixed issue with edges being marked sharp on import (even though they can't be, due to how the nif format works) when the normals weren't normalized, caused by Blender normalization being inconsistent.

Changed normal export to take sharp-marked normals into account. Copied over update_tangent_space from pyffi and changed it so that vertices with same normals and position, but different UV coordinated no longer have the same tangents (because tangent calculation depends on UV coordinate)

Changed select_unassigned_polygons to actually select in the original mesh (rather than the copy with tris).
