Fix for segfault when doing 'coc "seyda neen"'.

Browse source 
This is a fix for segfault:

==8683== Process terminating with default action of signal 11 (SIGSEGV)
==8683==  Access not within mapped region at address 0x0
==8683==    at 0x59DFE4: MWRender::Animation::handleShapes(std::vector<Nif::NiTriShapeCopy, std::allocator<Nif::NiTriShapeCopy> >*, Ogre::Entity*, Ogre::SkeletonInstance*) (animation.cpp:503)
==8683==    by 0x5A4ECE: MWRender::Actors::update(float) (actors.cpp:134)
==8683==    by 0x5937A9: MWRender::RenderingManager::update(float) (renderingmanager.cpp:168)

==8683==    by 0x51F9681: Ogre::Root::_updateAllRenderTargets() (in /usr/lib/libOgreMain.so.1.8.0)
==8683==    by 0x51F98CF: Ogre::Root::renderOneFrame() (in /usr/lib/libOgreMain.so.1.8.0)
==8683==    by 0x51F990C: Ogre::Root::startRendering() (in /usr/lib/libOgreMain.so.1.8.0)
==8683==    by 0x68A669: OMW::Engine::go() (engine.cpp:408)
==8683==    by 0x51CECB: main (main.cpp:254)
==8683==  If you believe this happened as a result of a stack
==8683==  overflow in your program's main thread (unlikely but
==8683==  possible), you can try to increase the size of the
==8683==  main thread stack using the --main-stacksize= flag.
==8683==  The main thread stack size used in this run was 8388608.

when doing 'coc "seyda neen"' when animations are enabled
(Animation::animate member variable is set to 1).
