Add utils modules

* disk.py

	Disk discovery

* fs.py

	Uses psutil to fetch fs usage information

* menu.py

	ogBrowser menu generation

* net.py: gets nic status information

	IP address, MAC address and ethernet speed.

* probe.py: probes mountpoints for operating systems

	Uses hivexget command to try fetching Windows installation
	information.
	Looks for /etc/os-release for probing linux systems.
