Progress for #463

• Setup appveyor
• Setup browser tests
• Automate integration tests
• Review if buster-syntax needs to be in the main bundle (other extensions aren't)
• when@3
• async@1
• lodash@3
• Await all other PRs referenced by Dependency / node support updates #463 to be merged and released
• Review Speedup startup #457
• What's the build for? The generated resources/buster-test.js is not in the latest version anyways Fix (or remove) doc/samples and resources/buster-test.js #472
• Why is sinon included part by part, rather than pkg?
• Do when/async/lodash really need to be exposed?
• Fix phantomjs on appveyor phantom simply crashes on appveyor, but there's an issue for this already: buster-server fails on headless mode on Windows 8 #434 (solution is cross-spawn-async)
• In framework-extension / wiring-extension, find a way to make prepend/append happen before ramp-resource's whenAllLoaded use a different hook to prepend, instead of a promise
• buster-cli should have better error reporting before process.exit
• ramp should have a configurable heartbeat timeout ramp should have a configurable heartbeat duration #471
• buster-test might have a race condition in mock verification - rebuilt buster-node on travis to reproduce random failures
• Use real version number, instead of 0.7.x in resource names
