Non-binding condition gets quoted

Alain Albertini

Hi,

It seems that when I try to build a non-binding "where" condition, the value still gets quoted, which prevents anything like the example from working:
https://editor.datatables.net/manual/php/conditions#Binding-submitted-data

This will generate a error indicating "unknown column 'xxx' in where clause.

Modifying Query.php at line 1056 for the following seems to fix it:

'query'    => $this->_protect_identifiers($key) .' '. $op .' '. $value
