making button filters functional

These commits make the button filters functional. Each click actually
rebuilds all the layers (unnecessarily expensive) by calling the
original layer construction scripts. Now though, the extra fields are
used to restrict the data. nc_centers needs a "ward" key because,
as-is, the schools map restricts by the school's ward (if the school is
not in the selected ward nothing appears on the map -- not very
interesting). For the neighborhood map, elementary/middle/high schools
are defined ONLY as places with grades 1-5/6-8/9-12, and public schools
are "Regular schools". Finding active buttons is stupidly complicated
because the onclick function happens before a given button is
activated/de-activated so you have to manually change the button you
click. I do this with a "toggle" argument, but I'm sure there is a
better way.
updating button "active" checking to toggle properly. School's are no liberally defined but there remain schools that don't serve any grades. I am logging those schools to the console so they can be tracked down and fixed in data.
intermediate push with more button changes: restoring wards to "schools" app.

It is not immediately obvious how to limit the schools dropdown menu because the schools.json file does not include ward number, grades, etc. That information is in the commute json. That said, I'll try quickly hacking transparent.js to read that information for all schools rather than just a cluster.
fixing buttons to reset dropdown menu after click.
add consolelog.js -- use log() instead now
schools.json has much more info now
filter buttons now work on both pages
