Problems combining bullet 3d with openrameworks

Hi,

I just updated ofxBullet to work with OF 0.9.0 and Visual Studio 2015. It's still a work in progress, but you can find it all here: https://github.com/prisonerjohn/ofxBullet/tree/hotfix-winblows

I've recompiled the bullet 2.8.2 libs and added x64 bit targets. I only updated two examples so far: SimpleExample and MeshExample (which uses the ofxBulletLib and property sheets). I'll update the rest and make a PR to the main repo over the next few days.

Let me know how it works out!
