Updated project files with debug / run configurations.
Add Q2Pack and Q2WPack to default build.
Add .obj as a supported filetype because the rest we support are already there.
Try skin.tga in the model directory as a last-ditch-effort to load model skins. This fixes all of the Quake2World models in Radiant.
Remove support for --libgl and Q3R_LIBGL. We should instead rely on GDK_GL_LIBGL_PATH, as GtkGlExt does and we must agree with it.
