Make AWstats default

Webalizer is pretty old and the latest release dates back to 2013.  
The generated statistics are even not really accurate, as mentioned here:  https://en.wikipedia.org/wiki/Webalizer#Criticism  

In conclusion I would appreciate it if the default value could be changed to AWstats.  
This merge request does address #3549
