@diosmosis I've renamed test methods, and changed test parent class to
PHPUnit_Framework_TestCase. Thanks for that review!
DI. Now it's ready to merge?
It was a wrong old test method
UsersManagerTest::testAddUserWrongEmail() that asserted that
ema'il<a class='mention' href='https://github.com/email'>@email</a>.com is invalid, but regarding RFC and new email validator(and http://isemail.info)
ema'il<a class='mention' href='https://github.com/email'>@email</a>.com is valid.
array('mx' => false, 'deep' => false) are default settings for
Zend_Validate_EmailAddress so I think we can just forget about it.
