Add name information to more layers

[gregallensworth]

Expanding on #1 so as to make the best of #4

Labels are displayed as the XXX_name layer, e.g. waterway_name and layer_transportation_name These are point layers generated by the OSM import tools, into wholly-new Db tables such as layer_transportation_name

However, the geometry-only layers such as water and waterway and transportation have minimal SQL queries for just the geometry This means that mouse-and-tooltip and click-info behaviors do not work properly -- no attributes are included.

Add at least the name field to these layers:

• [x] water
• [x] waterway
• [x] streets
• [x] building
• [x] poi
• [x] place
• [ ] park

There may be more in the future, but for the immediate dataset this would be an improvement.

building -- reworked some SQL functions, to expose the building field. The buildings have no name information, but the building at least indicates what the building is used for, e.g. "church" or "school"

[gregallensworth]

poi -- This already had the name fields worked into the functions and schema, and exposed via vectiles as well. I have set up tooltips for all poi features used in the current style.

[gregallensworth]

place -- Already done; this is the large place/region labels e.g. "Seattle"

[gregallensworth]

transportation -- Did some DB hacks to add a name field to this layer; updated the gh-pages demo as well

water -- easy peasey. 14 views, all from the same dataset. Now they have hover effects.

parks -- cannot The source layers do not have name information:
