LUCENE-1390: Added ASCIIFoldingFilter, a Filter that converts alphabetic, numeric, and symbolic Unicode characters which are not in the first 127 ASCII characters (the "Basic Latin" Unicode block) into their ASCII equivalents, if one exists. ISOLatin1AccentFilter, which handles a subset of this filter, has been deprecated.
