View source for User profiles disabled

If an empty file with the name <code>user_profiles_disabled</code> is placed in the eduke32 base directory, the game will use this directory instead of <code>Appdata</code> or <code>/home/user/.config/eduke32</code> to store user data.

This includes config files, screenshots, saves, the autoload directory and texture cache files. It also affects the commands [[readarrayfromfile]] and [[writearraytofile]], which would normally also read/write data from/to the profile directory.

The presence of <code>user_profiles_disabled</code> is similar to setting the launch parameter <code>-usecwd</code>, however, the latter parameter comes with additional effects.
