Libquery: fix missing image pointers from Mesh's UV layers.

Not really happy with this, could lead to a **lot** of callback executions...
But libquery foreach looper must go over **all** ID pointers,
otherwise remapping & co is broken!

A possible fix for future would be to have 'image slots' defined at root of poly/facetex layers,
and just a (short) index in each face/poly item - would also save a reasonable amount of memory...
