Correct invalid keywords.txt KEYWORD_TOKENTYPE

Use of an invalid KEYWORD_TOKENTYPE value in keywords.txt causes the keyword to be colored by the default editor.function.style (as used by KEYWORD2, KEYWORD3, LITERAL2) in Arduino IDE 1.6.5 and newer. On Arduino IDE 1.6.4 and older this will cause the keyword to not be recognized for any special coloration.
