[#31912] Generated passwords - longer and with special characters

By default, the generated password in Joomla! to 8 characters without any special characters (eg. $,%, @).

I suggest some improvement in security by default generate a 10-character password with special characters.

I applied a patch on Github.

Before sharing patch, it has been tested by me on the latest current version of Joomla 2.5 and 3 branches.

Test Procedure:
1 Create a new user account leaving the password field blank (send e-mail passwords must be enabled).
2 The generated password will not have any special characters - only letters and numbers.

and

1. Change password for @% + \ / '! # $ ^?:. () {} [] ~-_
2. Verify that you can log on.
