[gnome-nibbles] Apply bonus type HALF based on current length

[Iulian Radu <iulianradu src gnome org>]

commit 65ec002e0df02cf7416526f242abe3885f39498a
Author: Iulian Radu <iulian radu67 gmail com>

    Apply bonus type HALF based on current length
    
    When reducing the worm's length to half, the total length was actually
    the sum of the worm's length and the length that was going to be earned/
    lost if the worm previously consumed another bonus.
    
    Reduce the worm's length based on the length shown when the HALF
    bonus is consumed.
