add support for stripping accent marks from greek letters.
fix stripAccentMarks() to use libiconv stuff
so all languages are now supported.
fix wiktionary-based generation code so we can map
a word with accents stripped to the
word with the accents in place.
when user searches for a word without the
accent marks, we now also search for the same
word but with the proper accent marks.
still searched for stripped words even if
has a synset. fixed query lang
detector in SearchInput.cpp.
fix stack smash core.
