Implement increment/decrement on cache storage engines, using read/write by default and using atomic command on memcache

By default rails will update keys in memcached when using Rails.cache.write. Use :unless_exist => true flag to prevent existing keys from being overwritten.

Note that allow_concurrency = true means you need to verify_active_connections! to clear out connections assigned to stale threads.

Ruby 1.9 compat: force assert_select text encoding to the encoding of the regexp it's matching against.

Fixed that BenchmarkHelper should use controller.logger instead of @logger (which now apparently is gone)

Added ActionController::TestCase#rescue_action_in_public! to control whether the action under test should use the regular rescue_action path instead of simply raising the exception inline (great for error testing) [DHH]

If Rails doesn't respond to vendor_rails?, abort with an error asking
the user to run 'rake rails:update'.

Introduce ActiveResource::Base.timeout. This allows a timeout to be set on the internal Net::HTTP instance ARes uses (default is 60 seconds). Setting a low timeout allows ARes clients to fail-fast in the event of a unresponsive/crashed server, rather than cause cascading failures in your application.
