Update Externals/SFML to 2.1

- all files converted to unix line endings
- files from other subsystems and most of system have been removed
- include/SFML/System.hpp and include/SFML/Network.hpp modified to
  not include removed stuff
- IpAddress.*pp renamed to IPAddress.*pp to workaround git apply bug
  with case-only renames

/// s = L"hello"; // automatically converted from wide string
/// s += 'a'; // automatically converted from ANSI string
/// s += L'a'; // automatically converted from wide string

/// sf::String s;

/// a more optimized class if your program requires complex string
/// handling. The automatic conversion functions will then take
/// care of converting your string to sf::String whenever SFML
/// requires it.
///
/// Please note that SFML also defines a low-level, generic
/// interface for Unicode handling, see the sf::Utf classes.

/// \class sf::Time
/// \ingroup system
///
/// sf::Time encapsulates a time value in a flexible way.
/// It allows to define a time value either as a number of
/// seconds, milliseconds or microseconds. It also works the
/// other way round: you can read a time value as either
/// a number of seconds, milliseconds or microseconds.
///
/// By using such a flexible interface, the API doesn't
/// impose any fixed type or resolution for time values,
/// and let the user choose its own favorite representation.
///
/// Time values support the usual mathematical operations:
/// you can add or subtract two times, multiply or divide
/// a time by a number, compare two times, etc.
///
/// Since they represent a time span and not an absolute time
/// value, times can also be negative.
///
/// Usage example:
/// \code
/// sf::Time t1 = sf::seconds(0.1f);
/// Int32 milli = t1.asMilliseconds(); // 100
///
/// sf::Time t2 = sf::milliseconds(30);
/// Int64 micro = t2.asMicroseconds(); // 30000
///
/// sf::Time t3 = sf::microseconds(-800000);
/// float sec = t3.asSeconds(); // -0.8
/// \endcode
///
/// \code
/// void update(sf::Time elapsed)
/// {
/// position += speed * elapsed.asSeconds();
/// }
///
/// update(sf::milliseconds(100));
/// \endcode
