FLOW3:
* findObjectByIdentityProperties() now can handle multiple identity properties

TYPO3CR:
* removed use of PHP6 package string operations
* hasNode() on Nodes now massively performs faster for direct children
* Session now no longer register new nodes as dirty, speeds up handling of new nodes massively
* bindValue() no handles all Value types by using their string representation
* cleaned up splitName() in the storage and search PDO backends, refs #2891
* moved some PDO prepare() calls out of loops for speedup
* FLOW3 persistence query can now search for properties being objects
* started to rewrite QOM parsing in PDO search backend, needs more work!
