No support for schema names in itemTable, itemChildTable, assignmentTable and rightsTable.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create an $auth object and set $auth->itemTable = 'otherschema.AuthItem';
2. Try to create an auth item.

What is the expected output? What do you see instead?
Rights should do a proper insert to the database using provided table and 
schema name.

What version of the product are you using? On what operating system?
r140

Please provide any additional information below.
In components/RDbAuthManager.php on line 224 a query should be build using 
query builder, not written directly:
$rows = $this->db->createCommand()
->select(array('name','type','description','bizrule','data'))
->from($this->itemTable)
->join($this->itemChildTable, 'name=child')
->where($condition)->queryAll();

Probably rest of queries should be rewritten to use query builder. This 
properly quotes column names. See issue 56.
