Implemented Missing Functions
Functions for creating sprites and backgrounds and capturing from the
screen, tested thoroughly all appear to be working properly without
breaking any games. Also please note that Game Maker 7 and earlier
versions had the preload parameter for the replace, and create, and add
functions Game Maker 8 deprecated the parameter and Studio makes the
majority of these functions completely obsolete. So I also addressed the
issue with the missing overloads. Please merge when ready.
