The support for escaping chars like @ , \40 as described in xep 0106, was adjusted when subscribing new contacts. Added the encoding/decoding support for the char @, also as described in xep 0106, in the authentication proccess. The non-escaped username is now saved in the accounts.xml file int the 'emailmconf' field. The token is now generated automatically, but the user still keeps validating it. Added some icons.
