Replaced window close parameter with mutable flag.

Browse Source 
Replaced the GLFW_SHOULD_CLOSE window parameter with the
glfwWindowShouldClose and glfwSetWindowShouldClose functions, allowing
the setting of the close flag from any point in the program.

@section quick_window_params Retrieving window parameters
@section quick_window_params Checking the window close flag
Each window provides a number of parameters that can be queried with @ref
glfwGetWindowParam. Some are related to the window itself and others to the
OpenGL context. For example, to find out if the user is attempting to close the
window, either by pressing the close widget in the title bar or using a key
combination like Alt+F4, check the @c GLFW_SHOULD_CLOSE parameter.
Each window has a flag indicating whether the window should be closed. This can
be checked with @ref glfwWindowShouldClose.
When the user attempts to close the window, either by pressing the close widget
in the title bar or using a key combination like Alt+F4, this flag is set to 1.
Note that <b>the window isn't actually closed</b>, so you are expected to
monitor this flag and either destroy the window or give some kind of feedback to
the user.
@code
while (!glfwGetWindowParam(window, GLFW_SHOULD_CLOSE))
while (!glfwWindowShouldClose(window))
{
// Keep running
}
@endcode
You can intercept the setting of the close flag by setting a close callback with
@ref glfwSetWindowCloseCallback. The return value of the close callback becomes
the new value of the close flag.
You can also set it yourself with @ref glfwSetWindowShouldClose. This can be
useful if you want to interpret other kinds of input as closing the window, like
for example pressing the escape key.
