Fixed some errors

Fixed the following errors:

 777: // NOTE: Shader functionality is not available on OpenGL 1.1
 778: fn Shader loadShader(ZString vsFileName, ZString fsFileName) @extern("LoadShader");          // Load shader from |

This looks wrong, must @extern("TextToFloat") with that one.

[lerno]

This should be

fn bool isShaderValid(Shader shader) @extern("IsShaderValid");  // Check if a shader is valid (loaded on GPU)

Yes hehe... sorry just fixed quickly didnt think much ab it :p

Thank you!
