- cleaned up some javascript

Fixed: password match function blocked tabs incorrectly
Fixed: set focus on username input field threw an error if this field did not exist on a page

- Random password length: by default, generated passwords will have a length between 10 and 15 characters (instead of a fixed length of 10 characters).

Added SOAP support for mail module. Many thanks to Arkadiusz Roch & Artur Edelman from Tri-Plex technology
