My work for task-confirmation

@brutuscat I've chosen third-party Eloquent ORM (the same which Laravel uses) cause firstly there was no limitation for extending current code base (I don't know how much functionality are implemented for this moment). Secondly I think that you use your current Active Record realization a bit wrong. E.g why do I need to implement 'where clause' directly in model class and not in super class(see your Task model class)? It generates code duplication. (For example you need duplicate ```where()```, ```findOrCreate()``` etc. per model) You can easily compare it with Eloquent model class implementation and if there is not so much code to change you can easily migrate on this approach cause it very convenient and has good AR architecture. On the other hand why you don't use out-of-box ```Zend_Db_Table```?
