[Sugar-devel] Keep offline for Browse (offline bookmarks)

I've tried jar:, but there were numerous issues with navigating to
other pages. Also, it was quite hard to get Browse to actually open
that URI, it kept trying to prettify it.

On top of that, jar: has been deprecated because of security issues.

After investigating jar: I found out that it actually unzips things in
temporary storage anyway. So I could easily replace jar: with two
lines of code and not bother with its problems. The only thing my code
doesn't do that jar: does is very prompt cleanup.
