More Vim-like search behavior

Browse source 
This patch activates the last aborted search when pressing the search shortcuts
('n' or 'N').

To avoid confusion, and to make things more predictable, I've chosen to always
reactivate an aborted search starting from the beginning (or end, in case of
'N' or '?') of the current page, as opposed to Vim which continues from the
next search term each time the search is reactivated.

Searching using '/' or '?' doesn't center the view at the current search term
like when using 'n' or 'N', so we fix this here.

Also, I managed to work around the issue of the thin rectangular margins that
show around the previously-highlighted search terms after the search is aborted
(either explicitly or as a result of following links), by redrawing the page
widget (only if it's visible) instead of redrawing the rectangles covering the
highlighted search terms.
