Big set of changes to move the code closer to the proposed WebFoundation API. Major work includes:

	- Implemented new callbacks for WebResourceHandleDelegate. All delegates of WebResourceHandle
	  were updated to reflect this change.

	- Modified the way WebProtocolHandler creates protocol-specific responses.

	- Move WebResourceHandle API much closer to the final proposal. The public API on this class
	  is very thin now. Some private methods are still available to code inside Intrigue (to ease
	  the transition), and the dependencies on these private methods will be reduced over time.

	- WebResourceRequest and WebResourceResponse classes are now closer to their proposed APIs, but
	  work remains to be done with them.

	- Synchronous loading code received a large rewrite.

	And an extra:

	- Sped up implementation of file protocol handler. This protocol handler no longer kicks a thread for each file load.
