Web UI Overhaul

This has talked about a few times, here's solidifying it.

The web interface needs a serious overhaul: either from scratch or upgraded. We also need to decide how to better display the data, such as providing some visual to what subnets are children of others. (NIPAP does this with expand (+) and indentation)

Rough list of improvements:
- Enhance the way networks are listed visually. Current implementation mimics the API, returning a list, but a human expects more than that. Additional to easily identifying children from parents a configurable "description" attribute could be nice. An attribute name the interface will look for on a resource to render in a column without clicking all the way through - this would increase the CTRL+F / greppability.
- Login page, but that is described at #130
- Either configurable graph page or way to see a usage graph for any allocated resource

If anyone knows a more frontend/design experienced person that might make it easier
