Removed deprecated MinLength/MaxLength validation rules

Replaced occurrences of separate MinLength/MaxLength rules with Length validation rule.

Without these changes Symfony2 v2.2.0 will fail when updating the password and triggering a validation rule.

The final error that is displayed is:

FatalErrorException: Error: Maximum execution time of 30 seconds exceeded in /mywebapp/app/cache/dev/classes.php line 8856

The cause for this timeout is constant writing of deprecated validation method notices to the development log file:
