"tags" ⇢ "properties"

[jfirebaugh]

The specification and protocol buffer definition should use the term "properties", not "tags". "Tags" is OSM-specific nomenclature; "properties" is much more common in the Geo world.

In fact, our own principal libraries for vector tiles prefer "properties":

• mapnik-vector-tile
• vector-tile-js

I'm open to this being closed as woulda-coulda-shoulda but too painful to change, if that's the case. It's not a huge deal, I just wanted to invite some discussion.

I am quite fine with changing the name in the document in many places, but I do not believe we could do a minor bump and change the name of the field in the protocol buffer definition.

We should also revise the specification text to use the term "property" rather than "attribute".
