Added output support to TGAImage, SGIImage and newly-renamed DDSImage

classes. Added support to TextureIO for writing textures back to disk
via new TextureWriter plug-in interface. Added TextureConvert demo
which shows how an application might convert between arbitrary file
formats using these APIs, including automatic compression to DXT3
format when available.
