Added new methods to set uniforms in sf::Shader
Implements a new design for the shader uniform API. * Added Shader::setUniform() and Shader::setUniformArray() overloads for the following types: -> scalars: float, int, bool -> vectors: 2D, 3D, 4D -> matrices: 3x3, 4x4 -> arrays of basic types -> samplers (sf::Texture) -> conversions for SFML types (sf::Transform, sf::Color) * Added sf::Glsl namespace with GLSL-equivalent types * Deprecated Shader::setParameter() overloads Other related changes: * Refactored sf::Shader internals to avoid code duplication * Improved documentation * Added SFML_DEPRECATED macro to Doxyfile * Defined _SCL_SECURE_NO_WARNINGS to disable std::copy() warnings on MSVC
