docs(systemjs.web): auto-bootstrap option that creates its own AppModule and boots it.

For specific plunkers, e.g. "QuickStart (reboot edition)" PR angular#2762, that shouldn't have AppModule or main.ts
Rescinds the automatic bootstrapping and exclusion of `main.ts` in angular#2786 and angular#2756
Only autoBootstraps when `window.autoBootstrap === true`.
