Feature: Multisite mode

It would be great if the plugin got a Multisite mode. There get one option mode, including logging about the whole network after Network activation. Currently, it is necessary to activate the log mode and autorefresh, also some views in each site of the network for an item inside the logging screen.

@bueltge thank you for the suggestion. I'll consider making this multisite-compatible.
