* Fixed an internal bug which accumulated resources over time

* Nested composite nodes can now be exported into templates. A separate template for each nested composite node is created and referenced in its parent composite node. This also means that shift-dragging to copy nested composites works.
* Fixed layer delete bug which, in some cases prevented layers from being deleted in ZK (while they were deleted in 3dsmax) causing unwanted errors.
* Fixed if base layer ("0") is renamed and current layer is deleted nothing happens
* Fixed Zookeeper window dissapearing if it was saved and its bounds are outside the current monitor(s)
+ Added "Rename on double click" option to tree views (allowing to change the default single-click rename behaviour)

* Composite node inputs can now be specified as composite inputs of another view if that composite node is nested in a view. This also fixes a few bugs which stemmed from this limitation.
