TGA image loader for universal-editor

Believe it or not, those last screenshots showing polymolive displaying (somewhat flawed) textures on the model were not in the de facto TGA file format (TrueVision "Targa"), they were in Windows Bitmap (BMP) format. I had been converting all the textures to BMP format because it was easier to load the BMP files using the .NET System.Drawing API, which (being based on Windows' own GDI system) does not support more esoteric file formats like TGA. Fortunately, now TGA textures load PERFECTLY... though whether they'll display correctly on the model is another story, but the below screenshot proves that the textures load just fine when displayed in a System.Windows.Forms.PictureBox - so any errors with the model textures is an OpenGL issue and NOT a universal-editor issue!!!
