Removed duplicate include.
Added clipboard support on linux using X11.

We're still using SDL1.2, but now some functions use X11, so if we every fully switch to X11, we can keep at least some of the code.

Finished the material editor in the IDE. Rewrote screen shader bindings. Fixed depth buffer FBOs and depth buffer binding. Screen shaders now require explicit 'color' and 'depth' rendertarget bindings to access the original scene/screen render. Added an optional precision parameter to String::NumberToString. Numberous resizing improvements to UI controls and IDE props. Added DefaultShaderNoTextureHDR shader to hdr pack. Added a default REMOVE_EVENT Event type. Added Vector2 shader prop. Removed deprecated saving/loading code from Scene. Numerous bugfixes in shader code.
