If program can't find material file, Collada export fails with null exception.

If the material file isn't found, when it tries to write the materials to Collada it fails with a null value exception.

Materials in .cgf/cga files are fairly primitive. The default behavior for the material chunks should be to just create a placeholder with the material name, without grabbing any texture files. Creation of materials in Blender will be moved to CGF Importer, which will then use the appropriate .mtl file to load images, create shaders, etc.

This has been solved by creating default materials from the Cryengine files in the event that the material file cannot be found.
