Title: Allow add a condition telling the table to avoid ambiguity error.

When the joinWith() is being used in the search, may happen to have fields with the same name found in the tables.
I suggest a change to the function that adds the conditions understand disambiguation.

Thus, the following code could be used:
```php
$this->addCondition($query, 'tbl_Customer.id');
```
