Port to Ogre 1.9.0

[akien-mga]

I've tried to build Vertigo against OGRE 1.9.0 on Mageia 5, and after some tweaking to get the dependencies installed (ParticleUniverse and OgreOggSound), I hit errors relative to Ogre, namely (excerpt):

It would be nice to get the code base updated for recent libs, so that the game can still be built in recent environments (and maybe attract new contributors, or at least distro packagers?).

Can you publish your fork? I'll take a look at this soon. Would be nice to get this running again with the latest libraries, especially now that ParticleUniverse is open source which means this can get into the OSS channels!

My changes were pretty basic, it was mostly to make sure the libraries are found on my system, and overriding some of them bundled headers with newer ones from upstream. Since it did not work in the end, I did not keep my git clone.

But indeed, I packaged ParticleUniverse a while ago for the Summoning Wars game, so I would like to package Vertigo for Mageia too :)
