stardict_lib: remove dead poGet{Current,Next,Pre}Word iterators

Browse Source 
They aren't used at all by scdv, and thus aren't tested (meaning that
adaptions to the core lookup algorithms can be complicated because these
methods use them but aren't tested so there's no real way of knowing if
a change has broken the methods or not).
