SYNTAX:
guibutton,guibutton,guibutton = guiShowMessageBox ( string message, string boxType, string title [, string button1, string button2, stringbutton3] )
REQUIRED ARGUMENTS
* message - The message you want in the message box
* boxType - Either "warning","question","error","info".  Displays different icons accordingly
OPTIONAL ARGUMENTS
guiShowMessageBox allows for up to 3 buttons in the message box
* forceShowing - Ensures that nothing else but the message box can be clicked, besides gui elements created afterwards.
* button1 - A string of the first button that appears
* button2 - A string of the second button that appears
* button3 - A string of the third button that appears
Not specifying forceShowing will default to false.
Not specifying all buttons will only create that many buttons.  For example, specifying 2 buttons will only display 2 buttons.
Not specifying any buttons at all will default to one "OK" button.
All buttons hide the message box by default


RETURNS:
Returns 3 gui elements of the each button the gui window.  If these dont exist nil is returned instead.  You can attach these to a
onClientGUIClick event to do whatever you want.
