Simplify browser testing

npm run browser-test

Converted tests to "plain" commonjs--no boilerplate, except one sniff
for window.buster vs require('buster'), which we may also be able to
eliminate via browserify's -x switch. npm run browser-test builds
those into a single file: test/browser/tests.js and then runs
buster-static.

This simplifies things a lot.  There's no need for curl or curl
config, or the curl-privileged hoop jump.  It also gets rid of the amd
path/moduleid boilerplate.

Updated to jshint 2.x and buster 0.7.x.
