pass custom params in init

[juauzynhu]

If possible, pass GLFW args (like GLFW_TRANSPARENT_FRAMEBUFFER, etc) on .init params

eg.: cpx.init(100,100,"name", GLFW_FLOATING | GLFW_HOVERED)

Just added this feature. Now you can do:

ctx.init(600, 600, "Hello", decorated=False)

The whole list of possible arguments:

		bool resizable,
		bool visible,
		bool decorated,
		bool focused,
		bool auto_iconify,
		bool floating,
		bool maximized,
		bool transperent,
		bool focus_on_show,
		bool scale_to_monitor,
		bool full_screen

I did not upload this to pypi yet, but I will do it soonish as well as I'll update the documentation
