Title: Dependencies visualizer + UI enhancement

## Dependency Viewer

This pull request adds a viewer for the "callgraph" function dependency data contained in the dump-info dump file. It displays this information in a 3-tiered table:
```
-------
-------
+++++++
=======
=======
```
The selected element is in the middle, and the functions using that element are shown above. The elements being used by the element are below.

## Paper-Elements

To accommodate the dependency viewer, the UI had to contain tabs to toggle between the different data models. This either required either writing a complete tabs implementation, or using the tabs in Paper-Elements. Because I was already using Polymer, this was an easy transition.
