This change removes singletons for stats collection and signal
dispatching facilities, by making them a member of the Crawler class.
Here are some examples to illustrates the old and new API:
Signals - before:
from scrapy import signals
from scrapy.xlib.pydispatch import dispatcher
dispatcher.connect(self.spider_opened, signals.spider_opened)
Signals - now:
from scrapy import signals
crawler.signals.connect(self.spider.opened, signals.spider_opened)
Stats collection - before:
from scrapy.stats import stats
stats.inc_value('foo')
Stats collection - now:
crawler.stats.inc_value('foo')
Backwards compatibility was retained as much as possible and the old API
has been properly flagged with deprecation warnings.
