spider level. A new spider (InitSpider, not yet documented) was added to
provide initialization facilities.
Also renamed make_request_from_url to make_requests_from_url and allowed it to
return iterables.
Execution Manager:
* added control_reactor argument to delegate external twisted
reactor control (for example by twistd)
* now it loads spiders (if not already loaded)
* now it stars the log (if not already started)
* removed *args from configure() method
* removed **opts from runonce and start methods
Execution engine:
* added control_reactor argument to to delegate external twisted
reactor control (for example by twistd)
* changed some functions and method names for clarity
* improve handling of exceptions in st() method
* regrouped close_domain, closed_domain, and _close_domain method
for legibilty
Scheduler:
* replaced pending_domains_count (dict) by pending_domains (set)
* simplified some doc

constructor (domain prioritizers will be refactored later anyway) and
simplified Scrapy Manager code thanks to this.
Added make_request_from_url method to BaseSpider, splitting funtionality to
create requests from URLs which was previously done all in start_requests.
in this changeset:
* remove HttpException from engine and core exceptions
* replace dwmw ErrorPages with spidermw HttpError
* bugfix image pipeline media_to_download method when stat_key returns None
* documented
* moved from scrapy.contrib.downloadermiddleware.cache.CacheMiddleware to
scrapy.contrib.downloadermiddleware.httpcache.HttpCacheMiddleware
* settings prefix changed from CACHE2_ to HTTPCACHE_
