[WIP] Introduce new premium provider Heidelberg Huerdenlos

[1000miles]

This PR imports data from the new provider Heidelberg Hürdenlos for following attributes via a rake new task (huerdenlos.rake):

• osm_id=> poi_id (if there are any per record)
• provided_poi.wheelchair status
• provided_poi.url

Important: At the moment we do not fetch data for provided_poi.wheelchair_toilet, this needs further clarifications since Hürdenlos uses yes, limited, no and unknown for the toilet status while wheelmap uses yes, no and unknown only.

Example (dev env):

+------+------------+-------------+------------+--------------------------------------------------------------------------------------------------------------------------------------+---------------------+---------------------+-------------------+
| id   | poi_id     | provider_id | wheelchair | url                                                                                                                                  | created_at          | updated_at          | wheelchair_toilet |
+------+------------+-------------+------------+--------------------------------------------------------------------------------------------------------------------------------------+---------------------+---------------------+-------------------+
| 4366 | 4127557146 |           3 | yes        | http://www.heidelberg.huerdenlos.de/index.php?id=980&huerdenlos[module_ratings][action]=detail&huerdenlos[module_ratings][dbid]=3538 | 2017-05-17 15:28:39 | 2017-05-17 15:28:39 | NULL              |
| 4367 | 4176950906 |           3 | limited    | http://www.heidelberg.huerdenlos.de/index.php?id=980&huerdenlos[module_ratings][action]=detail&huerdenlos[module_ratings][dbid]=4441 | 2017-05-17 15:28:39 | 2017-05-17 15:28:39 | NULL

Important: At the moment we do not fetch data for provided_poi.wheelchair_toilet, this needs further clarifications since Hürdenlos uses yes, limited, no and unknown for the toilet status while wheelmap uses yes, no and unknown only.

I understand the column Hürdenlos Toilette in the file Bearbeitet_Hürdenlos_Wheelmap_Matching_nur_verknüpfbare.xls is unclear.

I suggest the following interpretation:

• If (Hürdenlos Toilette=VBF) --> toilets:wheelchair=yes
• If (Hürdenlos Toilette=NBF) --> toilets:wheelchair=no
• If (Hürdenlos Toilette=TBF && Wheelmap=grün) --> toilets:wheelchair=yes (reason: I checked some and they seem to be much stricter than we are)
• If (Hürdenlos Toilette=TBF & Wheelmap=Rot) --> toilets:wheelchair=no
• If (Hürdenlos Toilette=TBF & Wheelmap=Gelb) --> ignore toilets:wheelchair

Thanks for the clarification, @holgerd . That helps a lot! :) Will update the PR accordingly.
