Replace Spanish suffixes by Portuguese suffixes in the Portuguese snowball stemmer

On PortugueseStemmer.cs[1], there are a few suffixes in the PortugueseStemmer which I believe were copied by mistake from SpanishStemmer[2]:

• "log\u00EDas" should be "logias" (line 137)


• "log\u00EDa" should be "logia" (line 113)


• "uciones" should be "uções" (line 139)


• "uci\u00F3n" should be "ução" (line 120)

For more details, see the original report on nltk project:

Open PortugueseStemmer.cs and compare the listed suffixes with the corresponding entries in SpanishStemmer.cs. Replace the four specified Spanish forms with their Portuguese forms, then verify that the Portuguese suffix tables contain the requested spellings and no unintended changes.
