Fix node-front-end build rules and build/dep.mk

Build intermediate traceur.js with last-good node front.
./traceur combines bin/traceur.js with src/node code.
While self-compiling, we use last-known good bin/traceur.js
from git and now we use last-known good src/node.

Emit the build/dep.mk makefile rules in evalCodeUnit() step.
Don't automatically make build/dep.mk, its dependencies are too
complex.

Makefile: keep node/src, build test-list first, test wiki.

When saving node/src during build, cp rather than mv. That way the
working set is ok if git checkout aborts.
Build test/test-list first so test/runner.html works even if the build fails.
Add wiki as test dependency, so 'make test' builds everything.

Closes #603.
Remove inlineAndCompileSync and its use,  require.js.

The sync compile was only used for two test files.
These tests are now compiled explicitly in the Makefile.
The .traceur.js pattern for triggering compilation now is .generated.js;
the source files are in test/unit/es6.

Closes #606.
Safer build: copy src/node to build/node.

Add traceur-build that runs out of build/ and thus uses build/node/*.js.
Copy current src/node to build/node-save, restore last-good src/node,
copy to build/node, restore src/node. This reduces ways that src/node
changes can be lost by build shenanigans.

Use LoaderHooks for customization in src/node.

Move fileLoader from Loader to LoaderHooks; use fetch() per spec.
Pass fileLoader as arg to LoaderHooks, not property-set on Loader.
Remove src/node operations on InternalLoader, now extends LoaderHooks.
Remove loadSync() and friends
Move Loader evalCodeUnit to LoaderHooks.evaluateModuleBody (per spec-ish)
Driveby: correct WebPageTranscoder to succeed if run() after DOMContentLoaded.

Makefile rules for build/node.

The files in build/node are checked out from a previous git commit,
ie they are 'known good' versions of src/node files. Added rules to create or update
build/node when src/node/* changes. Removed the deletion of build/node upon success in
the build and added build/node to .gitignore instead.

Minimal Loader API.

Close to the spec: import(url, callback, errback),
  module(source, options, callback, errback).
Not in spec: loadAsScript(url, callback, errback),
  script(source, name, callback, errback).
Other functions removed
