 #Startup
 If wallpaper-reddit is run with the --startup flag, the program will wait on an internet connection.  Options for the startup can only be set in the config file.  They are under the [Startup] section: interval and attempts.  The script will try to make a connection to reddit.com $attempts times at every $interval seconds.  For example, the default setting is an interval of 3 and 10 attempts, so the script will try to connect to reddit every 3 seconds for up to 10 tries, giving a total of 30 seconds before the scrpit gives up.  As a reminder, this feature is only activated by the --startup flag
