[TreeTagger] Problem if TreeTagger does not generate a POS or lemma

[GoogleCodeExporter]

The analysis engine cannot deal with cases where TreeTagger does not output a 
POS and lemma.

- Allow dealing with cases that TT4J does not return a lemma or pos for a token.
- If TT4J does not provide a lemma, then do not create one. Before we created a 
lemma in this case using the original text as lemma. But since this is the 
behaviour from TreeTagger (not TT4J) as well, this is not necessary.
