/*
 * Functions to show the popup window
 * use ShowMacDialog when you want to control title, message and text on the button
 * ShowMacAssertDialog is used by assert
 * ShowMacErrorDialog should be used when an unrecoverable error shows up. It only contains the title, which will should tell what went wrong
 * the function then adds text that tells the user to update and then report the bug if it's present in the newest version
 * It also quits in a nice way since we call it when we know something happened that will crash OpenTTD (like a needed pointer turns out to be NULL or similar)
