In registration page,made changes to display feedback message 'Enter at least 10 characters' for password field.

Currently in registration page,the user is not notified with any feedback regarding the number of characters that the password field must contain, due to this the user might wonder why the register button is disabled after entering few character's say 6. The change will displays a feedback message 'Enter at least 10 characters' for password field until 10 Characters are entered.
