Changes

When an external [[demo]] lump is viewed using the [[Parameter#-playdemo|<tt>-playdemo </tt>]] [[command line parameter]], the automap can be accessed, and the [[IDDT|automap cheat code]] works. The automap is not accessible during a [[Demo#Built-in demos|built-in demo]], or while running a demo with the [[Parameter#-timedemo|<tt>-timedemo </tt>]] or [[Parameter#-fastdemo|<tt>-fastdemo </tt>]] switches; pressing the tab key in these modes brings up the game menu.
