Add more features

Currently the price does not match the product. There needs to be something to offer other than just a very basic scanner. Anyone can build this giveaway with very basic knowledge of programming. The name is also terrible, at least rename it to network scanner or something.

Possible features to add:
- Show device attached to local subnet
- Alert by email when new a MAC-address joins the network
- Timestamps when devices have been found to be active in network (automatic rescan every x minutes)
- Logging to file
- Show network usage /w timestamps (graph)
- Wake on LAN and other basic network features
- Scan for services / detect services silently when they are used
- Log predefined network activity to file (eg. HTTP GETs)
- Possibility to do some light data mining on logfiles directly from the GUI
