Compress (zip/tar) log when archiving. Filesize -90%

#1

Hey,
first of all, great service!
Just one small issue, that is nagging me since some time.
I am running wow off a M2 SSD, diskspace is rare. I would appreciate it, if the “archive” log function zips or tars the logfile.
This would decrease filesize by 90%.
Sure, you could delete your logs every month or so, but I like to keep stuff like that.
Maybe implement that as an optional option.
