#4572: Nominatim should handle hyphenation tolerantly

-----------------------+-------------------------
 Nominatim finds a street that has hyphens in its name only if the query
 uses the same hyphenation.

 For example, Nominatim will find the "Donau-Schwaben-Straße" in Passau if
 the search term is also writen with hyphens:[[BR]]
 [http://nominatim.openstreetmap.org/search.php?q=Donau-Schwaben-
 Stra%C3%9Fe%2C+Passau][[BR]]
 However, it will not find it if you search for "Donauschwabenstraße" (an
 entirely plausible spelling if you haven't seen the name in writing
 before):[[BR]]
 [http://nominatim.openstreetmap.org/search.php?q=Donauschwabenstraße%2C+Passau]

 Expected behavior would be that hyphenation, like capitalization, is
 ignored when deciding whether an element should qualify as a search
 result.
