JSTD adapter for running e2e tests

Couple of changes into angular.scenario runner:
 - add autotest config (runs tests when document ready)
 - update ObjectModel (forwards events)
 - use only one ObjectModel instance for all outputters
 - expose error msg and line number in ObjectModel.Spec and ObjectModel.Step
 - fix generating spec.ids
 - fix 'html' output so that it does not mutate ObjectModel

Couple of changes into docs / generator:
 - rename copy -> copyTpl
 - move docs/static into docs/examples (to avoid conflict with jstd proxy)

Running all docs e2e tests:
========================================================
1/ compile angular-scenario, jstd-scenario-adapter
>> rake compile

2/ build docs
>> rake docs

3/ start jstd server
>> ./server-scenario.sh

4/ capture some browser

5/ run node server to serve static content
>> node ../lib/nodeserver/server.js

6/ run tests
>> ./test-scenario.sh

+/**
+ * JSTestDriver adapter for angular scenario tests
+ *
+ * Example of jsTestDriver.conf for running scenario tests with JSTD:
+  <pre>
+    server: http://localhost:9877
+
+    load:
+      - lib/angular-scenario.js
+      - lib/jstd-scenario-adapter-config.js
+      - lib/jstd-scenario-adapter.js
+      # your test files go here #
+
+    proxy:
+     - {matcher: "/your-prefix/*", server: "http://localhost:8000/"}
+  </pre>
+ *
+ * For more information on how to configure jstd proxy, see {@link http://code.google.com/p/js-test-driver/wiki/Proxy}
+ * Note the order of files - it's important !
+ *
+ * Example of jstd-scenario-adapter-config.js
+  <pre>
+    var jstdScenarioAdapter = {
+      relativeUrlPrefix: '/your-prefix/'
+    };
+  </pre>
+ *
+ * Whenever you use <code>browser().navigateTo('relativeUrl')</code> in your scenario test, the relativeUrlPrefix will be prepended.
+ * You have to configure this to work together with JSTD proxy.
+ *
+ * Let's assume you are using the above configuration (jsTestDriver.conf and jstd-scenario-adapter-config.js):
+ * Now, when you call <code>browser().navigateTo('index.html')</code> in your scenario test, the browser will open /your-prefix/index.html.
+ * That matches the proxy, so JSTD will proxy this request to http://localhost:8000/index.html.
