Title: Create methods for loading shaders depending on GL version

- Load now uses ofShader to load shaders from path,
so we know for sure it will work the same way.
- Ensure FBOs are set to correct width/height when
allocate is called.
- Can set shader source for GL ES/2/3 by setting
specific strings in constructor, or by calling
loadVersioned.
- Can reload shaders from file without having to recompile.
