[Imports] YahooJapan/ALPSMAP imports

[Satoshi IIDA]

Thank you for comments!

> it is best to stop the imports and fix the data first, if possible.
I confirmed to dataset creator, he could do it. (although needs a bit times..)
So I will talk it out with Japanese mappers.

> the ~ character
I think it could be converted into ~ or - , and removing "m" letter in
the value, when we reconstruct the dataset.
But as the opposite opinion, "yh: WIDTH" is a mere reference value.
Wiki documentation is enough, I think.
(Of cource, the explanation should be added on wiki docs. I will add it later)

Very clear roadmap!
If we could change the .osm dataset, it can be substitute for step 2.

I know that anyone using OSM data (particularly in Japan) needs to support UTF but there's nothing to be gained by ~ using instead of something else.
