This may help on GC and/or be VM friendlier.

coverter_to_threejs.py: two new options and removed trailing whitespaces

Compressed textures with a single mip level have to use Linear min filter, instead of the default Mip filter.

This fixes colada keyframe example but breaks helpers. Time to refactor Helpers...

3DSMax Exporter - Corrected specular export, support Phong

Made a correction to the way the specular coefficient is exported; this was using the 3DSMax "Glossiness" attribute. It has been corrected to use the 3DSMax material "Specular Level". The "Glossiness" has been correctly remapped to the "Shininess" three.js attribute. 

Additionally included Phong shading, so the three.js Phong material will be used if Phong when used in 3DSMax - without this the bump maps are disregarded as they aren't rendered with Lambert materials (default material when unspecified). Blinn/Metal ShaderType materials will continue to be exported as Lambert.
