Controller::WasKeyReleasedThisFrame() is now keyboard->key_released() so
there is usually no need for a controller. They will completely disappear
when joystick axis binding has been ported to InputDevice.

Input was broken, as well as palette generation, and even texture
upload. Should be all good now.

The containers no longer force the user to use the ptrdiff_t type for
size information. For convenience, size() now always returns an int,
and the size_s() method offers a way to handle arrays with more than
2 billion elements. Internally, we still use ptrdiff_t, though.

Since so much code had to be changed, I took the opportunity to get
rid of capitalised accessors for classes that are lowercase.

Box objects (AABB) now have the long awaited extent() and center()
methods. Corners are now called “aa” and “bb” for convenience. The
WorldEntity class uses a box3 for its AABB instead of two vec3s.
This allows us to simplify a lot of verbose code.

Revamped thread communication
Fixed dynamic thread Add/Remove
Added unit-test for threads !!!!

Big FAT pass on windows-warning. It is better now.

scene so that g_scene can be deprecated later.

- removed 386 CR characters

on automake platforms, too.

compilation time for very little benefit and maybe even confusion.

that 2-year old "temporary Win32 hack".

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

avoid conflicts with the C++ stdlib.
