Fixed search options panel disappearance on startup

Trying to fix #156 and #131.

Yeah, but this messes up the hpaned position in fullscreen mode. For example, when width=1920, and hpaned_position>1440.

Alternatively, we can try checking hpaned_position >= width - 200, if you can confirm that it works for you.

    # HPaned position correction
    if ($CONFIG{hpaned_position} >= ($mainw->get_size)[0] - 200) {
        $CONFIG{hpaned_position} = ($mainw->get_size)[0] * 0.75;
    }

($mainw->get_size)[0] - 200)
also works, but why isn't width * 0.75 good?

In my case, in fullscreen mode, hpaned_position is 1676, which is more than width * 0.75, which is 1920*0.75 = 1440. So, checking for hpaned_position > width * 0.75 will evaluate to a true value and the hpaned_position will get set to 1440, which is not necessarily in this case.

Checking for hpaned_position >= width - 200 makes sure that the width of the search panel is not lower than 200 pixels, which should not happen under normal circumstances.

I'm still not sure what causes this annoying issue. Could it be a Gtk2 bug, or something?
