Logfile - Remove Domain Entry from Filtered Logfile

In the logfiles of the provider Puretec, a domain entry is added to each record. This causes the Webalizer to produce nonsensical output in the "Top Searches" and "Top User Agents" tables. By activating this option, the domain entry is removed from the logfiles, which enables correct analysis by the Webalizer. I dont't know wether this also works with the logfiles of other providers. If someone sends me such a logfile, I will check it out and integrate the function into the program.
