externals are mangled if a non-external with the same name is in the mangleMap

[dekdevy]

Shader 1:

void main() {
  vec3 light = vec3(1.0);
}

Shader 2:

out vec3 light;
void main() {
  light = vec3(1.0);
}

Even if the mangler is instructed to not mangle externals, the second shaders external light will be mangled.

This also applies to vector selectors, happening for the same reason. ( I suppose it will apply to pretty much everything that would otherwise be prevented from being mangled in the checks that come after the manglemap lookup )
I havent explicitly checked, but this would probably also happen within a single shader.

float x = 1.0;

=> float a=1.0;

vec3 test = vec3(1.0);
test.x = 5.0;

=>vec3 b=vec3(1.0);b.a=5.0;

Have a fix in v0.1.13.
