Fixes #3698, no additional select performed in Model::deleteAll() if $callbacks and $cascade are false

Fixes #2146, set 'foreignKey' => false and use association conditions to get custom join scoping
Fixes #3323, set 'foreignKey' => false to disable default conditions
Fixes #3627, added Model::$findQueryType to inform callbacks of the current find query type, i.e. 'count'
