[Imports] Tenerife streams import

[Rafael Avila Coya]

Hi, Frederik:

I was searching for ref:pht in the tagging plan of the wiki and I can't 
see no reference to that anywhere.

In point 4) of "Main steps" of the workflow, OSM users are asked for:

"Examine each way in the ToDo list,

     Locate the reference of the stream for this way in the location map.
     Search using the reference the stream in the list cauces.csv.
     Add the tags indicated in #Tagging Plans."

So they will have to use the ref:pht to find the name, but they aren't 
asked to add the ref:pht to the tags, only the tags present in the 
tagging schema of the wiki: name=*, alt_name=*, waterway=* and 
intermittent=* (plus the changeset tags).

Cheers,

Rafael.
