Use C++ printing and make std:: namespace usage consistent

This change
* changes printf to cerr/cout in all code except the debug_print_macro
* change the debug_print macro to have printf go to stderr
* change all instances where things are qualified with std:: to rely on using namespace std instead

This change touches a significant number of files, but most of the changes are simple in nature.
These are a few pieces you may want to review more closely:

tabs - As I mentioned in #7, my QT Creator IDE seems to have used spaces for all tabbing.  There were pre-existing tabs in the source.  Thus it doesn't line up always in github.  My thought is to just leave it since the new code is per standard and then clean this up in the upcoming tabs task.
global_basic.hpp - This is where the debug_print macro is defined.  I also added #include <iomanip> here.
video.cpp - It was using formatting specifiers within printf to print one decimal point.  I changed it to a C++ equivalent:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c++
if( m_opengl_version >= 1.3f )
			{
                cout << "Info : OpenGL Version " << fixed << setprecision(1) << m_opengl_version << " is below the optimal version 1.4 and higher" << endl;

                //Restore cout format settings (so that we don't change them for the entire game)
                cout.unsetf(ios::fixed);
                cout << setprecision(6); //6 is the default in C++
			}
			else
			{
                cerr << "Warning : OpenGL Version " << fixed << setprecision(1) << m_opengl_version << " is below version 1.3" << endl;

                //Restore cerr format settings
                cerr.unsetf(ios::fixed);
                cerr << setprecision(6);
			}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

That was tested with this console program:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c++
#include <iostream>
#include <iomanip>

using namespace std;

int main()
{
        cout << "Starting precision: " << cout.precision() << endl;
        cout << fixed << setprecision(1) << 3.333 << endl;
        cout.unsetf(ios::fixed);
        cout << setprecision(6);
        cout << 34.333 << endl;
        return 0;
}

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
--In this program, I fix it to always print 1 decimal place.  Once done, I want to restore the default.  I have to unsetf because of the design of C++.  I then set the precision to 6 to restore the default.  Once I print again, it prints exactly 3 decimal points for the last number.

I tested using this command:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c++
LD_LIBRARY_PATH=/home/datahead/boost_libs/lib ./testinstall/bin/smc 1> stdout.log 2> stderr.log
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Here are the log files from my test:
