Moved Lua script object destruction to a function.
Destroy the old Lua script object before creating new.
Unref the object specific event handler functions when destroying Lua script object.
Queue only one large work item per thread for threaded Octree & View operations.
Protect the network replication dirty sets with mutex if nodes/components are inserted during the threaded update phase.
Fixed renderer raycasts returning wrong distance.
Added caseSensitive parameter to several String functions.
Added option to convert file extension to lowercase in GetExtension() and GetFileNameAndExtension() functions.
Removed unnecessary lowercase conversion of extensions, and complicated string compare logic.
Optimize cache friendliness of Drawable bounding box update by including the local-space bounding box in the base class. Not used in all subclasses.
Optimize Drawable zone handling by making the zone pointers raw pointers instead of weak. Now finding a drawable's zone can be performed in the threaded view preparation phase.
Removed unnecessary collection of whole visible scene bounding box; it is not used anywhere.
Renamed Octree::Resize() to Octree::SetSize()
When destroying a scene, destroy root-level components first so that child node components are detached from their internal structures and can be destroyed faster in turn.
Use raw pointers instead of weak pointers in Octree update/reinsertion lists for some performance gain.
Temporary objects are by default not shown in the editor.
Added trigonometric functions which take degrees argument into the C++ API, not just script.
Edited the Billboards sample.
Made the Urho3D logo in the samples slightly transparent.
Fixed build of samples.
Removed line to disable MinSizeRel build type in CMake script as it seems to have no effect any longer.
Removed unused function to get AnimationState by C string of animation name.
