[TYPO3-mvc] Extbase query objects - bitwise matching

Big warning here: I kindly ask anyone adding new SQL constructions in 
Extbase to _at least_ open a bug/feature request in DBAL bug tracker (on 
http://bugs.typo3.org) to ask for official support of the operator in 
t3lib_db and its XCLASS ux_t3lib_db (for other DBMS).

This is really important as I still want to be able to run Extbase 
extension on a non-MySQL DBMS at some point in the future and I need to 
keep track of what's going on in extbase which is issuing "direct" 
queries to the DBMS.

Cheers
Xavier
