Added a new LW dataset object
Added lw_dataset serialization support
Reworked normal generation code so that it matches LW approach
Normals are now generated, according to mesh material's vertex smoothing angle setting
Merge pull request #7 from kbiElude/normals_should_be_calculated_as_in_lw

Normals should be calculated as in lw
Merge branch 'master' into lw_dataset_stores_smoothing_angle_info
Added stub body for lw_material_dataset
Refactored the exporter plug-in so that separate C files hodl separate plugin responsibilities
Surface information is now extracted by the LW plugin
collada_data_effect now exposes UV map name if description of one is included in source file
Vertex smoothing angle info is now exported from LW. When loading the dataset, the angles are updated. Normals data is not re-generated yet.
Vertex smoothing angle info is now correctly merged with a scene instance
Merge pull request #8 from kbiElude/lw_dataset_stores_smoothing_angle_info

Lw dataset stores smoothing angle info
Memory leaks fixed
Merge pull request #10 from kbiElude/ref_counting_issues_in_scene_viewer

Memory leaks fixed
LW extraction plug-in now verifies that surfaces with duplicate name use the same property values
VSA info is now cached per mesh layer pass
Fixed the lighting issues visible in the 'bloki' scene
Scene viewer now correctly renders to a sRGB framebuffer
Added mesh dataset template
