enable BDD tests for different tokenizers

The tokenizer to be used can be choosen with -DTOKENIZER.

Adapt all tests, so that they work with legacy_icu tokenizer.
Move lookup in word table to a function in the tokenizer.
Special phrases are temporarily imported from the wiki until
we have an implementation that can import from file. TIGER
tests do not work yet.
