Fix for oF v. 0.10

[alptugan]

In ofxShaderFX_LightingShader.cpp edit line 354-355 as follows;
m_normalMatrix = ofMatrix4x4::getTransposedOf(m_cam->getModelViewMatrix()); m_shader.setUniformMatrix4f("normalMatrix", m_normalMatrix.getInverse());

Also, line 439 should be updated as follows;
glm::vec4 eyeSpaceLightPos = glm::vec4(m_lights[lightIndex]->getGlobalPosition().x,m_lights[lightIndex]->getGlobalPosition().y,m_lights[lightIndex]->getGlobalPosition().z,1.0) * m_cam->getModelViewMatrix();
