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.
