Title: DateRange constraint

Added DateRange constraint and appropriate translations in russian and english.

Date format by default is d/m/Y, but easily can be overriden by format property of constraint, f.e.:
```php
/**
* @Assert\DateRange(
* min = "01.01.1930",
* max = "01.01.2012",
* format = "d.m.Y"
* )
*/
protected $birthday;
```
This is my first commit to symfony components so feel free to request any additionals - write docs, improve something or so on.
