Updated version number after 3.3.0 dev release
Added createObject() interface
Added support for Lua 5.2 and osg::Object creation from within Lua scripts.
Moved code across to use lua_userdata to manage pointer to osg::Object that is ref()/unref()
Added support for automatically select Lua 5.2 is it's available, then falling back to checking for Lua 5.1 otherwise.
Cleaned up line endings
From Stephan Huber, "attached you’ll find a bunch of fixes + enhancements for iOS and OS X based on current trunk. I incorporated + tested the submission from Colin Cochran, so his submission is not needed anymore.

* fixed a bug with multi-touch and touch-id-generation on iOS and OS X. (will fix a bug reported by Colin Cochran, without ditching the existing logic)
* removed unnecessary warning-flagss when generating xcode-projects via cmake, will enable the usage of OSG_AGGRESSIVE_WARNING_FLAGS
* added support for 10.9 (OS X)
* new cmake-variable: IPHONE_VERSION_MIN, this will set the deployment-target (previously hard-coded) If you set the IPHONE_VERSION_MIN to something like 7.0 osg gets compiled also for 64bit (amd64)
* cmake defaults now to the clang compiler if IPHONE_VERSION_MIN > 4.2
* cmake now sets some xcode-settings so the compiler uses the c++98-standard (clang defaults to c++11, w/o this I got a lot of linking errors)
* removed include-dir for avfoundation-plugin as not needed on OSX/IOS.
* enhanced the ios-example, will now show multitouch-information on a hud (similar to the  osgmultitouch-example), and more importantly, will compile + link out of the box
* small enhancements for the osc-device-plugin (send only one msg for MOVE/DRAG, even if multiple msgs/event is enabled)
* better memory-handling for the zeroconf-plugin
* fixed a possible bug in the rest-http-plugin when receiving mouse-events.
* incorporated a fix from Colin Cochran "forwarded touch events are not transformed into the GL UIView“
"
Implemented preliminary readNode/readImage support in the lua plugin allow a lua script to create a scene graph as return it.
Added get/set method to Serializer to allow pointer passing without going through InputStream/OutputStream.
Laurens Voerman, "my cmake (2.8.10.2 generating for Visual Studio 11 Win64) doesn't like
include(${CMAKE_MODULE_PATH}/FindPackageHandleStandardArgs.cmake)
in CMakeModules/FindLua52.cmake
changing to a more common
    include(FindPackageHandleStandardArgs)
solves my problem."
From Laurens Voerman, compile fix for VisualStudio
From Pjotr Svetachov, "With the new osg::Geometry the binding for arrays now default to undefined. This breaks previously working code in osgAnimation::RigTransformHardware where the arrays got an undefined bounding and because of this the bone indices and weights were not loaded by the shader. Here is a little patch to fix this."
Added set/get to the ImageSerializer and removed some redudent comments
