Wrong LinkedHashMap order when load data

[Former user]

prize_cashBack_fixture: &cashBackPrize
    "[prizes][0][bonusPrize]": "9"
    "[prizes][0][options][19][value]": "25"
    "[prizes][0][options][20][value]": "3"
prize_cashBack_sendEmail_fixture:
    <<: *cashBackPrize

when I load( using new Yaml().loadAs(file, LinkedHashMap.class)) this data I have different order. see attached screenshot

see #351 Test nodes' order kept during merge.

fix #351 Now we preprocess keys for MappingNode and remove duplicates (keeping the last one). No need anymore to reverse values list for propper merging (it was done to fix http://code.google.com/p/snakeyaml/issues/detail?id=139). Added processDuplicateKeys method can be used to throw exeption in case of duplicate keys (see #337)
