Super lazy load view paths in development mode (no indexing or caching at all). Switch layout finders to use view path api to take advantage of cache.

This reverts commit 3be9134d.

Remove deprecated render_component. Please use the plugin from http://github.com/rails/render_component/tree/master

* Make the old deprecated relative_url_root still set the value as it's still used by mongrel
* Set the default from the ENV value when the file is required, not at runtime.

Simplified the logging format for parameters (don't include controller, action, and format as duplicates) [DHH]

Let fresh_when actually do the head(:not_modified). Cleaner and we get the filter halting for free then.

Added stale?/fresh? and fresh_when methods to provide a layer of abstraction above request.fresh? and friends [DHH]

Return processing lock to dispatcher, the finer grained lock was incompatible with the reloading in development mode.

This commit also adds ActionController::Dispatcher#dispatch_unlocking -- non-locking version of dispatch.
It's named anologously to POSIX {getc,getchar,...}_unlocked functions.
