Create terrain-classic-lines and terrain-classic-background variants

[almccon]

Currently I've got terrain-classic (which includes everything) and terrain-classic-labels as the only two variants. We also need terrain-classic-lines and terrain-classic-background (which omits labels and lines).

Look at https://github.com/stamen/toner-carto to see how this is done. Also, compare terrain-classic.yml and terrain-classic-labels.yml in this repo, and extend the pattern to the other two variants. Also examine the tessera.json file in this repo to see how we serve up the variants.

For comparison, here are what the deployed styles look like: http://maps.stamen.com/terrain-background/#13/37.7625/-122.3973 http://maps.stamen.com/terrain-labels/#13/37.7625/-122.3973 http://maps.stamen.com/terrain-lines/#13/37.7625/-122.3973

@almccon I'm not seeing terrain-classic-labels in the makefile to generate the corresponding xml file. When I run make [terrain-classic-labels] I get the following output:

make: *** No rule to make target `[terrain-classic-labels]'.  Stop.

[almccon]

Are you actually using those brackets around the make target? make terrain-classic-labels should work, but not make [terrain-classic-labels].

The reason there's not terrain-classic-labels in the Makefile is because magic. It hits the % wildcard which tries to make a %.mml file.... and that triggers the %.yml wildcard... so as long as terrain-classic-labels.yml exists, then make terrain-classic-labels should work.

Need to create the following YML files:

• [x] terrain-classic-lines.yml
• [x] terrain-classic-background.yml
