[Vimperator] quick find regression

[Mike Lowell]

I've been using Vimperator since <0.4.1 -- it's great!

...but the quick find (forward-slash to search) doesn't seem to work
well in later versions, and I assume it's something I'm doing wrong --
I'm hoping you guys can point me in the right direction.

I have two machines with Vimperator.  One I keep updated as new
versions come out, now at version 0.5.3.  The other I haven't updated
since 0.4.1 because of the search issues.

On versions >0.4.1 I've found that searches only work within the
current page.  If I open a tab, switch to it, and then try to search,
it doesn't work.  If I reload the page, then search works again.  I
often find myself opening a handful of tabs at once, and wanting to
search through them all.  With the post-0.4.1 search behavior this is
rather unproductive.

How to test:
   1) Open google.com
   2) Search for something
   3) Press "f" (QuickHint) and hold shift while entering a hint to
open that link in a new tab
   4) Press "gt" (next tab) to switch to the newly opened tab
   5) Press "/" (Quick Find) and then type something you see on the screen
      - For me, nothing happens
   6) Press "r" (reload) and retry #5 again: now it works as expected.

Any suggestions?  Is it just me?  Thanks!
