move abbreviation computation into import phase This adds precomputation of abbreviated terms for names and removes abbreviation of terms in the query. Basic import works but still needs some thorough testing as well as speed improvements during import. New dependency for python library datrie.

normalization:
- ":: lower ()"
icu: normalise simplified to traditional chinese The conversion is unambigious in most cases, so that the information loss is minimal.

improve normalization Make sure all special symbols are removed during normalization already. Those won't be interpreted in any way because they are unlikely to be searched for.

introduce sanitizer step before token analysis Sanatizer functions allow to transform name and address tags before they are handed to the tokenizer. Theses transformations are visible only for the tokenizer and thus only have an influence on the search terms and address match terms for a place. Currently two sanitizers are implemented which are responsible for splitting names with multiple values and removing bracket additions. Both was previously hard-coded in the tokenizer.

sanitizers:
- step: split-name-list
- step: strip-brace-terms
extend ICU config to accomodate multiple analysers Adds parsing of multiple variant lists from the configuration. Every entry except one must have a unique 'id' paramter to distinguish the entries. The entry without id is considered the default. Currently only the list without an id is used for analysis.

token-analysis:
make token analyzers configurable modules Adds a mandatory section 'analyzer' to the token-analysis entries which define, which analyser to use. Currently there is exactly one, generic, which implements the former ICUNameProcessor.
