Updated the scripts to read from ~/.antix-session/wallpaper.conf
*if this is non existant copy from template in /usr/share/antix-settings/wallpaper/ to the users home directory

Updated the scripts to read the help file from the new template (/usr/share/antix-settings/wallpaper/help.txt), rather than ~/.antix-session/wallpaper/help.txt. Though the option is still in the wallpaper.conf file to use a custom help file.
