Bug 13800 - Diacritics not mapped

Bug 13800 - Diacritics not mapped

This patch adds a mapping for the lower case ð character to word-phrase-utf.chr ( Ð was already mapped to d)

To test:
1. Add a record with the  ð character (Arnaldur Indriðason is an example author)
2. Rebuild zebra
3. Search for your record using d instead of ð and verify it is not found
4. Apply patch and copy word-phrase-utf.chr to the appropriate folder
5. Restart and rebuild zebra
6. Search for your record using d instead of ð and verify it is found
