Fixes bug 1073593 - Fixed bugzilla links in Super Search.

@peterbe r?
It doesn't hurt either. This whole `window.DYNAMTIC_PAGE` stuff feels like a hack that adds noise. But I totally understand what you're trying to achieve. 

I think we should take this opportunity to do some necessary refactoring. 

There are 3 places where we use bugzilla.js, right?
* Top crashers
* This supersearch facets page
* The report list (via `report_list_bugzilla.js`)
Two of them can't rely on `window.onload` to fire. On the the Top Crashers can. 

The `Bugzilla` function exposes two functions: `transform_with_data()` and `fetch_without_data()`. How about we tuck those into `Bugzilla` as private closures and just expose one function called `run()` or `enhance()`. Then, your `search.js` can do `Bugzilla.run()` and `report_list_bugzilla.js` can do exactly the same and we can leave, at the bottom, a `$(Bugzilla.run)` for when it gets run on onload time. 

Actually, if we do this we can figure out why the `enhanceBugLinks` function does more than just `transform_with_data()` and `fetch_without_data()` and why this isn't needed in the report list.
