Improve query page

[djmelik]

The query page is more or less a simple shell at the moment.

We need to improve the page. At the moment, I'd like to do the following:

1. Add additional information when returning routes, eg. source, destination, amount.
2. Add an input box for user to enter the number of paths to return.
3. Add a graph showing paths (/w hops) from source to destination for visualization.
4. Translate node public keys to aliases so that it is more intelligible.

Open to all suggestions and recommendations.

Progress so far:

I need to still do #1 + #2. We should also rewrite this entire page as it's really poorly done.

Wow, that looks really awesome!
