[sldev] Support for PNG images available...

[Phoenix]

It should be noted that PNG files will soon not be accepted as  
textures, and we are unlikely to directly incorporate PNG support  
into the asset system. We are looking toward making it possible for  
prims to reference external websites for texture information, which  
is where PNG textures would start to come into play.
