Carlos Aragonés cdaa54f5d6 Direct mode (#23)
* update documentation

* Fix typo

* Added some examples

* changed window names

* Minor fix

* renamed callback setters (added _set_)
Direct / Poll Mode for asking events:
 bool            mfb_is_window_active(struct Window *window);
unsigned        mfb_get_window_width(struct Window *window);
unsigned        mfb_get_window_height(struct Window *window);
int             mfb_get_mouse_x(struct Window *window);            // Last mouse pos X
int             mfb_get_mouse_y(struct Window *window);            // Last mouse pos Y
float           mfb_get_mouse_scrool_x(struct Window *window);     // Mouse wheel X as a sum. When you call this function it resets.
float           mfb_get_mouse_scrool_y(struct Window *window);     // Mouse wheel Y as a sum. When you call this function it resets.
const uint8_t * mfb_get_mouse_button_buffer(struct Window *window);  // One byte for every button. Press (1), Release 0.
const uint8_t * mfb_get_key_buffer(struct Window *window);           // One byte for every key. Press (1), Release 0.

* Minor fixes

* Fixes related to mouse poll

* Minor fix on Win64
