Ext.form.field.VTypes - IBAN

[anton.dimitrov]

I checked the forums and couldn't find any IBAN validation so decided to do one by myself.
The regular expressions are the same as the ones used in ZEND framework for validating IBAN(s) so I presume they work..

Update: (30.05.2012)
- fixed a bug with the replacing of characters. The characters must be treated as a regular expressions otherwise only the first occurrence is replaced.
