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
