Revert 185709

> Set up V8 bindings for extension/app APIs when they're first used, not on
> context creation. This should gives us a significant reduction in extension/app
> startup time and slightly better memory usage.
> 
> It also gives us better error messages, the chance to complete the 
> implementation of API features, and eventually the ability to expose select
> extension APIs (e.g. extension.sendMessage) to web pages.
