Refactor the implementations of AssociatioCollection#delete and #destroy to be more consistent with each other, and to stop passing blocks around, thus making the execution easier to follow.

Correctly update counter caches on deletion for has_many :through [#2824 state:resolved]. Also fixed a bunch of other counter cache bugs in the process, as once I fixed this one others started appearing like nobody's business.

Support the :dependent option on has_many :through associations. For historical and practical reasons, :delete_all is the default deletion strategy employed by association.delete(*records), despite the fact that the default strategy is :nullify for regular has_many. Also, this only works at all if the source reflection is a belongs_to. For other situations, you should directly modify the through association.

Make record.association.destroy(*records) on habtm and hm:t only delete records in the join table. This is to make the destroy method more consistent across the different types of associations. For more details see the CHANGELOG entry.
