Fix Shader::compile() error output.
Fix Shader::compile() error output.

Because Debug outputs chars as numbers, it displayed the following:

    compilation of fragment shader321 succeeded ...
    compilation of vertex shader322 succeeded ...

instead of

    compilation of fragment shader 1 succeeded ...
    compilation of vertex shader 2 succeeded ...

Now I will forever know that ASCII code of space is 32.
