Added options browser_tests using the generator and js handler framework.

This patch turned out to be fairly large.  Let me describe the ultimate goal:
- To write WebUI tests in javascript, with as little C++ as possible for the simple case, yet powerful enough to support more complicated cases.  options.js illustrates the simple case, and print_preview.js illustrates the complicated case.

Original changes:
- Refactored test_tab_strip_observer into test_navigation_observer so that it could be used by itself without needing the TabInsertedAt logic, which PrintPreview needs when there's no TabContentsWrapper available.
- Added assertEqualsArray for comparing two arrays shallowly (javascript == fails).
- Provided logic in WebUIBrowserTest and in the javascript2webui.js generation script to allow browsing to a url with preload of injected javascript.
- Corrected test_navigation_observer to wait for the right notification before calling callback (which runs after the page's javascript is loaded but before its onload).
- Added guts to define OS_* ifdefs for javascript to test for disabling tests.
- Moved the handler from settings_browsertest.cc to settings.js
- use __proto__ when overriding chrome to allow other members to be seen (commandLineString, e.g.)

Additions made during review:
- Switched to generative mechanism: TEST_F, GEN, which output during generation, and register during runtime.
- JS fixtures provide configuration members
- Add configuration hooks to generate in C++ test function
- Output directly to .cc file rather than needing hand-made .cc file which includes the generated file.
- Changed preload to take testFixture and testName.
- include and use mock4js to ensure handler methods are called.
- auto-generate the typedef WebUIBrowserTest testFixture unless overridden.
