Add api pt_objects

API pt_objets with a possibility to querry on network, commercial_mode, stop_area, line and route.
Infact, it's just a parameter with 0 as default value. For each querry to api places if there is no result, jormungandr send a second appel to kraken with 1. In this cas the function find_partial_with_pattern is used which is based on ngram.
