Network explorer

A DevTools extension to interpret network requests in real time within a friendly way.
Main functions:
1. Network requests could be manually / automatically loaded into the extension.
2. Users could define custom filters to load requests they want.
3. It could display these requests in a table.
4. It could transform headers and contents of requests/responses into json object and display them as tree-like structures. Currently version only supports pure json requests and dwr request.
5. In these tree-like structures, users could copy and search nodes.
6. Jsonlizable strings could be detected automatically and show up in popups.
