Camera & vector.cpp : Fixed shifted_perspective crash with almost zero FOV.

Added utils.h : GetRandom(Array<T>) : gets a random element in a template list with weight logic.
                T FindValue(char*) : Find the value of a safe enum from the given name (when GetName is implemented)
                swap(T&, T&) is now in here too.

the old and useless BitField class.

currently works for images (SDL and GDI+ loaders) and sound samples.

hardcoded and only the fractal demo uses it, but everything will eventually switch.

but we can now create shared objects for each project; only the testsuite
is not building properly because of issues with STLport, and EglApp is
deactivated because AndroidApp should have precedence.

libraries only work with the Visual Studio runtime.

functions; also remove a lot of idiotic "using namespace std" from the
codebase.

the NaCl instance object. Now we properly override main() and we can at
