updated examples
remove commonsense.js (can be generated from commonsense.py)
improved sentiment() function (thanks Colin Molter @ tevizz.com)

- pattern.text:
	- Tokenizer now handles emoticons
	- Sentiment class now detects emoticons
	- Sentiment class has a labeler (MOOD for emoticons, IRONY for "(!)")
	- sentiment() now accepts patter.vector.Document or dict.
	- Both the lexicon and the labeler are easier to extend with Sentiment.annotate() or Sentiment.load(xml_file_path)
- English: bootstrap unknown adverbs from known adjectives
- French: bootstrap words without diacritics
