Title: Added validation and SQL expressions for ORM Fields.

Did a lot of work.

* Added model validation. Issue #51
* Fixed the problem with expressions and validation ( Kohana_BadData_Exception ). Issue #59
* Now the "default" can be NULL in Field settings. Now using ```array_key_exists``` instead of ```isset```.

I hope you will accept this soon.
