[xbmc] Add missing include of <utility>

[Paxxi]

This is a bit oppinionated, moved system includes to the bottom to try and avoid masking missing includes.

[Paxxi]

jenkins build this please

[Paxxi]

ok test again without cstdlib changes
jenkins build this please

[Montellese]

I always keep system includes at the top trying to follow the C++ Google Coding Guidelines.

[Paxxi]

@Montellese I did that as well until recently. The issue with it that I can see is that it hides missing includes in the headers

Lib.h

std::string a;

Lib.cpp

#include <string>
#include "Lib.h"

a = "yada"; //builds fine

User.cpp

#include "Lib.h"

a = "yada"; //build error

[Paxxi]

Seems like the google guidelines sticks them somewhat in the middle
https://google-styleguide.googlecode.com/svn/trunk/cppguide.html#Names_and_Order_of_Includes

[Montellese]

Yeah they put the include of the header belonging to the source file at the very top followed by C system includes, C++ system includes and then local includes.

[Paxxi]

That style is fine by me, I'll update this

[Paxxi]

so updated to google style include, broke pvr by reordering includes so there's some forward declarations and new includes added.
jenkins build and merge please

you would do me favour if you refrained from doing cosmetics in core. it is really painful rebasing VideoPlayer on this.

[Paxxi]

sorry about that @FernetMenta I'm done with these major clean-ups now for a while so should hopefully not cause you any more pain.
