Add Basic Network Info and VM Type

[su-haris]

Thought having a VM Type in Basic System Info and a Basic Network Info would make the YABS more informative/complete.

Sample outputs:

This PR has been merged. I've made some tweaks in 84f47e8 to add wget calls (if curl isn't installed), eliminated the extra call to ip6.me, and added an opt-out flag to allow users to skip the network info lookup/output.
