 Contains global GUI functions, which will
 later be accessible from every GUI script/file.
 So far, only the message box-related functions
 are implemented.

// @desc:       Displays a new message box. So far, we can only display one message box at
//              a time, since the message box is based on one base-object which is modified
//              according to the parameters. Later, we should probably be able to create GUI
//              Objects (like the message box) at runtime.
