If we don't block notebook button-press-event, it will affect search box,
when double click on search box button or search entry, it will then add
a new page with focus, which is what we don't want.
So, block this event when search box is visible, and unblock it when
search box is show off.
User can search their terminal by search box. Search is based on vte.
Default accel-key is CTRL+SHIFT-F, it will then show up a search box
at right bottom of the page. User can search by hitting Return to search
next, or hitting Return with Shift to search previous, or using next/prev
button to search.
ESC or anyother focus-out of search entry will hide the search box.
NOTE: it will only search on last focus terminal if the terminal has been
split out.
