First bunch of fixes for the NewTabPage + WebSnap chain.

It seems clear (to me) that they leaks memory, so they urgently need
fixes. And a complete redesign.
This is just a first (the easiest) part of it:
- Removed some unuseful methods,
- Added some documentation for the WebSnap class
- Cleaned code, in general
