Added functions. Renamed wrong named functions e.g. *_event to *_f

There was a few missing functions as of Allegro 5.0.8 that I have found.
Here is the patch for that.
As well as renaming a function (al_load_ttf_font_entry) to [al_load_ttf_font_f](https://www.allegro.cc/manual/5/al_load_ttf_font_f) as that is its correct name.
