fixes bug 908469 - Show all metadata in the individual report page

Anybody r?

The big change here is that there's a new tab on the report index called "Raw Details".
[As you can see here](http://cl.ly/SYYR)

What this code does it basically removes most reading from the raw crash from the main "Details" page instead, on the "Raw Details" no keys are hardcoded. It basically loops over all keys (that are in RawCrash.API_WHITELIST if don't have the `view_pii` permission).
