Added BIC ( ISO 9362 ) Code Validator

I have created a BIC code validator. Within the European SEPA payments region BIC codes are required together with IBAN numbers for transactions, so this could be very useful in conjunction with the IBAN validator.
I will remove the code for defining the special message. To make the validator thin, the special messages can be handled by triggering the [events](http://bootstrapvalidator.com/settings/#events).
